When people hear “millions of requests per day”, they imagine big clusters, Kubernetes dashboards, and five-digit cloud bills. Coupyn runs on $50/month. Coupyn was built solo — no investors, no team, no over-provisioned services. The challenge was to serve global traffic and track live analytics for nearly a million e-commerce companies while keeping infrastructure dirt cheap. Instead of scaling up, the entire stack was designed to waste nothing. Frontend Angular 20 SPA hosted on a small DigitalOcean droplet. Pre-rendered HTML for SEO, served by Nginx.

Intro Hi, guys! In this post we're going to talk about Next.js routing. This time we will only cover the core concepts of routing and in another post we will learn more about advanced concepts for a complete guide. In this guide I am going to use TypeScript. If you use JavaScript, just remove the types where necessary. The Core Route Files Dynamic Routing Typescript Helpers To define routes in Next.js, we use file-system based routing, which mean we use files and folders from within our app. When installing the Next.js app using: npx create-next-app@latest Next.js will create a folder app. You can safely delete everything inside it to remove the noise. This is of course not necessary, but I recommend doing it just to see every file in action without those boilerplate code from Next.js.…  ( 11 min )

If you’ve ever heard that “Java supports only single inheritance”, you might think Java is limited compared to languages like C++ that allow multiple inheritance. But the truth is... Java gives you the best of both worlds — simplicity and flexibility — without the messy diamond problems. Let’s break it down 👇 🧩 What Is Inheritance in Java? Inheritance allows one class to acquire the properties and behaviors (fields and methods) of another. It’s one of the core pillars of Object-Oriented Programming (OOP). class Animal { void eat() { System.out.println("Eating..."); } } class Dog extends Animal { void bark() { System.out.println("Barking..."); } } public class Main { public static void main(String[] args) { Dog d = new Dog(); d.eat(); …  ( 7 min )

One of the cool things about the way we've architected Hypertune is that experiments aren't something you reference directly in your code. Instead, they're created in the Hypertune dashboard and inserted into the rollout logic of a feature flag. Many teams manage feature flags and experiments separately, often using different systems for each. As a result, they end up with separate “experiment flags.” When testing a new feature, that means checking two flags in code: Your main feature flag — to control rollout to internal users, beta testers, etc. Your experiment flag — to split traffic between variants. At first, this might seem reasonable. But it quickly introduces complexity — and risk. In theory, the experiment flag should only be checked if the main flag is true. A user should only en…  ( 7 min )

I’ve always loved both maths and coding, but I never found a space where the two truly merge. So I decided to build one myself: MathHacks. It’s a weekend “mathathon” where participants build creative maths-based projects — visualisations, puzzles, small tools, or any idea that blends maths and creativity. Think of it as a hackathon, but for maths. The first MathHacks starts in 8 days and it’s completely free and open to everyone — students, developers, or anyone who enjoys problem-solving. Why I built it: I wanted a place to experiment with maths in a fun, hands-on way. I wanted something that feels creative, not competitive. I wanted a small, community-driven space for maths + coding lovers. If that sounds like your kind of weekend, come join in at the first mathathon I’d love to see what you come up with!  ( 6 min )

Introduction I found a way to avoid the well-known problem where “infinite scroll resets after a browser back,” using a modal that combines Next.js App Router’s Intercepting Routes and Parallel Routes. Even after using the browser back action, the scroll position of the infinite list is preserved. You can try it yourself with this demo app. This is a Next.js framework–specific approach, but I hope it helps anyone who is facing—or has faced—this problem. Notes This post does not explain the low-level details of Intercepting Routes or Parallel Routes. The main goal is to convey how the app feels when infinite scroll is combined with a URL-addressable modal built with Intercepting + Parallel Routes, via the demo app. The context is a web application, not a native app. Infinite scroll UIs h…  ( 10 min )

​FastAPI is getting more and more popular, as is building agents. Developers building agentic systems are starting to turn to FastAPI as one of the more ergonomic web frameworks for building endpoints and then adding on a Model Context Protocol (MCP) layer so that AI agents can discover and invoke those endpoints as “tools”. For example, with FastAPI-MCP you can take an existing FastAPI application, attach mcp = FastApiMCP(app) and mcp.mount(), and your endpoints become usable by an LLM-based agent with minimal extra work. But when it comes time to deploy your agent, how should you go about it? TL;DR: Heroku is great to start, but you pay for convenience with higher tiers, less control, and platform lock‑in. Defang keeps the Heroku‑like workflow but deploys your FastAPI app into yo…  ( 9 min )

In modern data workflows, APIs are everywhere — powering everything from model inference to data extraction. Yet, handling API failures gracefully is often neglected by data scientists, who tend to focus on analysis and modeling while treating fault tolerance as a “software engineering problem.” However, failure handling is not just an engineering nicety — it’s what makes a data pipeline resilient, automated, and production-ready. When your data pipeline processes hundreds or thousands of files via APIs, a single timeout or upload error can halt the entire process. You depend on external systems — their uptime, latency, and error messages are outside your control. Failures aren’t binary — some require retries, others should be skipped or gracefully degraded. Without a structured strategy, …  ( 8 min )

If you’ve ever watched your site slow down under traffic or worse—collapse during a peak moment—you’ve felt the sting of inadequate performance testing. But what kind of test would have saved you? Load or stress? And why does it matter? This isn’t just a definition battle. It’s about making the right calls across your dev, QA, and SRE teams. It’s about knowing what to test, when, and how to automate it at scale. And most of all, it’s about bringing your testing culture from reactive fixes to proactive engineering. Let’s break it down and build it back up—Gatling style. In software testing, both load testing and stress testing measure how systems behave under pressure, but the key is in the type of pressure.

Erase and Evolve: Selective Amnesia for Ethical Graph Neural Networks Imagine your AI stubbornly promoting outdated or biased information. Re-training from scratch is costly and inefficient. What if you could selectively erase unwanted knowledge from its memory, like deleting specific nodes from a social network without affecting the overall structure? That's the promise of graph unlearning. It's about surgically removing the influence of specific data points or connections in a graph neural network (GNN) without drastically impacting the model's overall performance or requiring a complete retraining. The key is to strategically "forget" information by focusing on the influence of connections, prioritizing the removal of high-impact edges.

Getting data from modern websites is not the same as it used to be- today, most websites render their data dynamically making it hard for traditional web scrapping tools to obtain any data. In this project: The Africa Energy project, we are going to use different tools to obtain data about Energy Indicators across 54 African countries for the years 2000 - 2022 from the The Africa Energy Portal. The project features: a web scrapper that extracts JSON data from API network responses. The Africa Energy Portal is a dynamic webpage that contains information about energy indicators across 54 African countries. The indicators are energy access, supply and technical aspects related to energy. The indicators are further broken down into sub-sectors such as 'Population access to electricity-National' which shows the percentage of people with access to electricity on a national level etc. The project uses the following technologies: a. Python for developing the web scrapping logic The scrapper utilizes Selenium to automate browser interaction such as loading the page and selecting all required themes, years and countries for precise data extraction. The scrapper obtains all the selected fields of the data ie; id, name, score, unit, region name, indicator topic, indicator source, indicator name, indicator group, year, url The data is extracted in JSON format and appended to an empty list before it is flattened and converted to csv format. Working on this project has been nothing short of a learning experience from the thought process of understanding the project, to learning of different ways to execute the project, to implementation of the same.

TL;DR Hybrid work is here to stay, but thriving in it requires a deliberate mix of technology, culture, and soft‑skill development. This guide walks you through the current hybrid landscape, shows how to build a robust communication framework, cultivates trust, aligns productivity processes, and highlights practical ways to upskill your team—including a quick look at tools like softskillz.ai for targeted coaching. When the pandemic forced many companies to go fully remote, most organizations discovered that a binary “office vs. home” model was too limiting. The hybrid work model—where employees split time between a physical office and remote locations—offers flexibility, broader talent pools, and often higher employee satisfaction. Yet it also introduces friction points: misaligned expec…  ( 12 min )

Why Interoperability Matters in Healthcare? For example, a patient visits a primary care doctor, is referred to a specialist, goes in and out of lab visits, and then winds up in the emergency room. Each provider collects information. But if their systems do not talk to each other, important information can be overlooked. That can result in repeated tests, delayed diagnoses, or even dangerous errors. EHR, LIS), smart connected devices, and the user interfaces for patients and medical staff.(Source: ScienceSoft) Improved decisions around care: Physicians can view their full patient history instead of fragmented bits. Increased efficiency: No duplicate lab testing or unwarranted imaging. Lower costs: Sharing data cuts down on waste and bolsters value-based models of care. Empowerment of the…  ( 9 min )

The concept of the T-shaped engineer isn't new. It's been around, quietly championed by forward-thinking tech leaders and organizations. But in 2025, as LLMs transform how we build software, this professional archetype has evolved from "nice to have" to essential. Picture the letter T. The horizontal bar represents breadth - a working knowledge across a wide range of technologies, methodologies, and domains. The vertical stem represents depth - expert-level mastery in one or a few specific areas. A T-shaped engineer might have deep expertise in distributed systems architecture while maintaining conversational fluency in frontend frameworks, DevOps practices, data engineering, and security principles. They can collaborate meaningfully with specialists across disciplines because they underst…  ( 7 min )

When I started building a Chrome extension using the WXT extension framework and displaying UI components, everything looked great on the demo site, and Tailwind CSS was working perfectly. But the moment I injected my UI into website on LinkedIn... BOOM—my entire styling look ugly and small hole UI. Button lost their padding, text lost font family, margin reset etc. At first, I Thought--- "This must be a path issue... maybe css not import on react index file." But the actual reason was something deeper- When you build UI components in the Shadow DOM feels like a perfect solution: ✅ No CSS conflicts At least, that’s what I expected.

I recently attended GOTO conference in Copenhagen (https://gotocph.com/2025, you can find the slides for some of the presentations there) and would like to share some of the interesting topics. This is about organisations, but I think it has even wider application. There are 2 types of organisations which differ only by the answer to the question: are people bad or good? These 2 approaches can be seen in my opinion everywhere when there is a group of people which need to follow any rules. This can be for example how the city authorities deal with passengers as far as transportation is concerned. However, the forest is rare. There are also quite many desert people who like the yellow and in fact most of the organisations are like Sahara. I think the key is just to realize these 2 landscapes exist and know which one suites you best to be able to work effectively. https://tidyfirst.substack.com/p/forest-and-desert https://martinfowler.com/bliki/ForestAndDesert.html  ( 6 min )

Last month I was joking with a friend about possibly traveling to Bali in December. I didn’t search it, didn’t message anyone about it, and didn’t even type the word “Bali” anywhere on my phone. And yet — the next day my Instagram Reels were full of Bali travel videos. Coincidence? Or does Instagram secretly listen to us through our phones? This question — “Is Instagram listening to me?” — pops up in conversations everywhere. The short answer: almost certainly not in the way people imagine. But the full answer needs a look at how recommendation systems work, why coincidences feel eerie, and what data apps do have access to. How recommendation engines predict what you want to see Instagram’s feed and Reels recommendations are powered by machine learning models that examine a lot of signals.…  ( 7 min )

The concept of autonomous agents, software that can operate, transact, and make decisions on-chain without constant human supervision has been around for a while. However, widespread adoption has been hampered by incompatible frameworks, isolated registries, and trust assumptions. ERC-8004 is a proposed Ethereum standard designed to address these challenges by providing a minimal yet extensible framework for agent discovery and trustless interaction. The standard defines three core registries: Identity: Assigns each agent a unique ID and links it to off-chain metadata describing capabilities, supported protocols, and domains. Reputation: Creates an on-chain audit trail of client-authorized feedback, enabling reputation tracking without storing all data on-chain. Validation: Supports task …  ( 7 min )

A Usabilidade para além do Front-end Quando falamos em "usabilidade", é quase automático pensarmos em interfaces bonitas, botões no lugar certo e telas que respondem rapidamente. Em resumo: a experiência do usuário final. Mas e se eu disser que a usabilidade é um conceito que deveria ser aplicado muito antes do front-end? Que ela começa no coração do sistema: o back-end. Um back-end com boa usabilidade não é sobre ter uma "interface gráfica bonita" (afinal, o "usuário" aqui é, na maioria das vezes, outro desenvolvedor ou sistema). É sobre criar uma experiência fluida, intuitiva e eficiente para quem vai consumir, manter e expandir o seu código. Pense no back-end como a cozinha de um restaurante.

But I thought I'd put together a Quickfire article about it to help spread the word, for anyone (such as those new to PHP) who may not be aware of it. match Expression in PHP The match expression allows you to compare a value against multiple conditions and return a given result (although a result doesn't necessarily have to be returned). It's similar to a switch statement in the sense that you can define "branches" based on different conditions. However, a key difference is that the match expression uses strict comparison (===), whereas a switch statement uses loose comparison (==). This means that with match, the types of…  ( 10 min )

Today I finally understood what makes React so powerful — state. Once you realize that your UI is just a reflection of state, React suddenly clicks. I created a small component that shows three steps: Learn React ⚛️ Apply for jobs 💼 Invest your new income 🤑 It includes “Next” and “Previous” buttons to move through steps, and a close button to hide the section. useState, I learned how to control what appears on screen based on the component’s state. Update State Based on Current State When updating a value using its previous value, always pass a function to the setter: setStep((s) => s + 1); That ensures React always uses the latest version of state — even with multiple updates. One Component = One State Every component has its own state — completely independent from others. UI as a Function of State The best way to think about React is: 🖥️ UI = f(state) Whenever your state changes, React re-renders the UI to match. When to Use State Use useState for data that should change over time or control the UI, like: Whether a modal is open Which step the user is on A toggle or input field If a value doesn’t affect what the user sees, use a normal variable instead — not state. 👉 Use state for anything dynamic. Understanding state changed the way I see React. thinking in terms of state transitions. Now, every time I build something dynamic, I ask myself: “How should my component look when this piece of state changes?” And that’s when React truly starts to feel alive. ⚡ I’ll keep experimenting with multiple states in one component and later explore Context and Reducers to manage complex state.  ( 7 min )

In previous posts, I’ve introduced some of the key syntax and features of Turbine, a Markdown-inspired scripting language. out parameter, a mechanism for returning multiple values from a function, similar to how C and C++ handle it. In Turbine, a function can only have one return value. But sometimes, you want to return a main result and an additional status flag, for example, when you want to detect division by zero in a divide() function. Many scripting languages, such as Python, can easily return multiple values using tuples: def divide(a, b): if b == 0: return 0, False return a / b, True result, ok = divide(10, 2) That’s convenient and expressive. references or pointers to return additional results: int divide(int a, int b, bool &ok) { if (b == 0) { ok = f…  ( 8 min )

They don’t tell you this in bootcamp, but coding is basically emotional damage with syntax. 😅 One minute you’re like: “I’m a genius — I just solved a bug!” And the next minute you’re like: “Why is this semicolon ruining my entire life?” Let’s be real — we’ve all been there. Coding isn’t just about logic, it’s about emotional resilience. You’re not just building software — you’re building character. 😂 Here’s the truth nobody says out loud: Even the best developers Google the same question five times a day. We all copy-paste from Stack Overflow like it’s a sacred ritual. We all say “just one last test” 47 times before pushing to production. But here’s the beauty in it — Coding teaches you how to keep trying even when nothing works. It teaches you patience, problem-solving, and humility. And sometimes… it teaches you new swear words. 💀 So if you’re feeling stuck or frustrated, remember — every great developer once broke down over a missing bracket.

Introduction In cloud environments, organizations often segment their IT infrastructure into multiple virtual networks (VNets) for better security, performance, and management. For instance, a company may separate core IT services such as DNS and security from departmental workloads like manufacturing or R&D. However, in many cases, applications and services across these networks still need to communicate securely for example, when a manufacturing app needs to access a shared DNS or authentication service hosted in the core network. This is where Azure Intersite Connectivity comes in. By implementing Virtual Network Peering, you can connect multiple VNets in Azure, allowing traffic to flow privately through Microsoft’s backbone network without requiring VPNs or gateways.

Every click, swipe, and voice command that feeds into artificial intelligence systems passes through human hands first. Behind the polished interfaces of ChatGPT, autonomous vehicles, and facial recognition systems lies an invisible workforce of millions—data annotation workers scattered across the Global South who label, categorise, and clean the raw information that makes machine learning possible. These digital labourers, earning as little as $1 per hour, work in conditions that would make Victorian factory owners blush. These workers make 'responsible AI' possible, yet their exploitation makes a mockery of the very ethics the industry proclaims. How can systems built on human suffering ever truly serve humanity's best interests? The modern AI revolution rests on a foundation that few i…  ( 27 min )

Hey, Flutter fam! Samuel here from Tech With Sam - your go-to for turning mobile dev headaches into high-fives. If you're like 70% of us in the community right now, you're knee-deep in building killer UIs with Flutter, but that backend? It's a nightmare.

Introduction In the part 1 we introduced our sample application. We basically used AWS Lambda Functions like GetProductByIdHandler where we extended io.micronaut.function.aws.MicronautRequestHandler and injected DynamoProductDao and other services by using Jakarta EE jakarta.inject.Inject annotation. While this is a valid approach, sometimes you have existing Micronaut REST application which runs on containers or servers, and you'd like to port it to Serverless with as little effort as possible. As we use here DynamoDB we're locked-in, so it's more about making our application portable between AWS services like EC2, ECS (also with Fargate), EKS (also with Fargate) and Lambda. Of course, you can replace DynamoDB repository layer with RDS, Aurora, Aurora Serverless or newly released Aurora…  ( 12 min )

Have you ever felt overwhelmed by the extensive use of frameworks and advanced technologies to build a simple portfolio website? Same here, which is why I chose to keep things simple by developing it using only HTML, CSS, and JavaScript. Here is how I did it: After finishing my resume, I felt something was missing: it was a place to showcase my skills, certifications, projects, and contact details in a way that was interactive and easy to explore. I only used HTML tags to display various sections and their information to mirror the resume document on the webpage. Then I started with using basic CSS code to change the font color and size so that the content becomes more readable.

Unlocking AI: The Simplicity Revolution in Reinforcement Learning Tired of reinforcement learning (RL) models that feel like black boxes? Do you dream of AI that not only performs well but also explains why it made a particular decision? Current RL approaches often involve complex neural networks, making it tough to understand their logic and adapt them to new situations. Imagine you want to teach an AI to navigate a complex maze. Traditionally, this meant training a neural network for countless iterations, with little insight into the strategy it was developing. A new approach uses decision trees directly as policies. This leads to interpretable rules, like "if the corridor is clear, move forward, else check for an opening to the left". Optimizing these tree-based policies efficiently, …  ( 7 min )

Welcome to Day 12 of the #80DaysOfChallenges journey! After chasing the longest word in a sentence on Day 8, today's challenge, finding the longest word without using len(), took things to a new level. This beginner-friendly task pushed me to rethink a familiar problem, diving deeper into manual counting, loops, and logic. It's like solving the same puzzle but with a twist that forces you to understand the gears behind Python's built-in tools. The goal was to find the longest word in a user-provided sentence, but with a catch: we can't use Python's len() function to count characters. Instead, we manually count each word's characters using loops, returning both the longest word and its length as a tuple. This challenge was a fantastic exercise in manual iteration, string manipulation, and l…  ( 10 min )

Email is still a crucial communication medium for companies, but it also ranks among the top platforms targeted by cybercriminals. Scams such as phishing, spoofing, and business email compromise (BEC) lead to financial losses in the billions for businesses annually. To combat these risks, implementing email authentication protocols like DMARC has become vital for safeguarding domain reputation and ensuring trustworthiness. DMARC, which stands for Domain-based Message Authentication, Reporting, and Conformance, is a protocol designed to help domain owners stop unauthorized usage of their email domains. It operates by confirming whether an email that appears to originate from a specific domain is actually sent by authorized servers. If the verification fails, the email can either be rejected…  ( 8 min )

I'm currently working on a software designed more than a decade ago. It offers a plugin architecture: you can develop a plugin whose lifecycle is handled by the software. The tough part, though, is how you access the platform capabilities: via static methods on singletons. @Override public boolean start() { var aService = AService.getInstance(); var anotherService = AnotherService.getInstance(); // Do something with the services var result = ...; return result; } There's no easy way to test the start() method. In the old days, Mockito developers had pushed back against this feature, and the only alternative was PowerMock. The decision was reversed in 2020 with the 3.4.0 release, which introduced static method mocking in Mockito. I liked the previous situation better. M…  ( 7 min )

An exception is an unwanted or unexpected event that occurs during the execution of a program (i.e., at runtime) and disrupts the normal flow of the application. Java Exception Handling is a way to detect, handle, and recover from unwanted or unexpected events (exceptions) that occur during the execution of a program. It allows the program to deal with runtime errors gracefully, without crashing, by providing alternative flows or meaningful error messages. Example: Imagine you’re using a food delivery app. You place an order, but your internet disconnects for a moment. Instead of crashing, the app shows a message: "No Internet Connection. Please try again." This is possible because of exception handling. The app catches the error and shows a friendly message instead of terminating . An…  ( 9 min )

After seeing an example on cassidoo's site, I decided to add an "AI Transparency" page to my site as well. Both she and the post she links make a really good point about how, if a person or company is transparent about how they use AI, it helps us trust that their work is more authentic in general. They recommend adding a page to your site (e.g. /ai) that details how you make use of generative AI (or not). From the simplest "No posts on this site are written with generative AI," to a longer, more detailed breakdown, the idea is not to cover your bases with legalese, but to be authentic, clear, and real. It's not a bad thing to use AI, necessarily. It's a tool like any other, and a user needs to understand how it works--pro's, con's, strengths, and dangers. But it's good to be open about it to help people understand and gain context for your work. And if you do decide to add one to your site, you can add your site to this public database of /ai page-having sites!  ( 6 min )

Once in my life, I tried to step down from the engineering role and kick off my own startup. The outcome? Well, I failed - the harsh reality of 90% of all startups. Yet, I don’t regret it, although it was a hard time until I ran out of cash and realized the idea wasn’t as groundbreaking as it had seemed at the beginning.

Three years ago, I started the Japanese Property Price Forecasting project to analyze and predict second-hand apartment prices in Japan. It was a great learning experience, but like many early projects, it lacked a structured pipeline and modern machine learning best practices. Recently, I revisited the notebook and modernized the workflow. Here’s what I added and improved. Previously, the notebook handled categorical and numeric features manually. Now, it uses a full scikit-learn Pipeline to cleanly separate numeric and categorical preprocessing: Numeric features: imputation with mean + standard scaling Categorical features: imputation + one-hot encoding (handling unknown categories safely) This makes the workflow cleaner, easier to maintain, and fully reproducible. Instead of a simple regression, the updated notebook uses LightGBM with hyperparameter tuning. This allows the model to achieve better performance while keeping the training process efficient. Old column names had spaces and special characters, which could cause issues with pipelines. All columns are now sanitized (_ instead of spaces and symbols), making the notebook pipeline-friendly and more robust for experimentation. The notebook now loads CSVs dynamically, making it easy to handle multiple files without hardcoding paths. Updating old projects is a great way to apply what you’ve learned over time. In this case: Cleaner, maintainable code Better reproducibility Stronger model performance Ready for future extensions (feature engineering, explainability, or deployment) You can explore the updated notebook here: Japanese_Property_Price_Forecasting_v2.ipynb If you’re curious about structured ML pipelines or modernizing legacy notebooks, this is a small but practical example of the process.  ( 6 min )

One of the biggest obstacles for call centers to manage customer experience is noise. Agents working in hybrid or remote environments battle barking dogs, keyboard clicks, and street chatter that disrupts professionalism and clarity. The AI noise cancellation for call centers helps remove background noise, improving voice fluency, and ensuring every interaction sounds calm, confident, and human. Industry estimates suggest that poor audio quality can increase average handle time (AHT) by 15–20%, as agents and customers repeatedly ask for clarification. When calls become frustrating, customer satisfaction (CSAT) scores drop—and even skilled agents struggle to sound composed. For QA teams, reviewing noisy recordings wastes analysis time and lowers scoring accuracy. That’s why modern contact…  ( 9 min )

When you start learning backend development, it’s easy to focus on features, getting APIs to respond, connecting to the database, or just making it all work. In my projects built with FastAPI, I follow a simple but consistent pattern for error handling. For Example: from fastapi import APIRouter from sqlalchemy.exc import SQLAlchemyError from app.logger import logger # custom logger from app.database import get_db from app.models import Student router = APIRouter() @router.get("/students/{student_id}") def get_student(student_id: int): try: db = get_db() student = db.query(Student).filter(Student.id == student_id).first() if not student: logger.warning(f"No student found with ID {student_id}") return {"error": "Student not found"} logger.info(f"Fetched student: {student.name}") return {"student": student.name, "email": student.email} except SQLAlchemyError as e: logger.error(f"Database error while fetching student {student_id}: {e}") return {"error": "Database connection failed"} except Exception as e: logger.error(f"Unexpected error in get_student API: {e}") return {"error": "Something went wrong, please try again later"} Here’s what’s really happening behind the scenes: Every error is caught from database issues to unexpected runtime exceptions. Logs are categorized info for successful events, warnings for missing data, and errors for critical issues. No internal crash leaks to the user. Instead, users see a clean, friendly response while I get detailed error traces in my logs. The logger I use writes all messages to a local file, but also integrates with CloudWatch for live monitoring when deployed. It’s one of those invisible systems that keeps everything steady. Over time, I’ve learned that a stable backend isn’t the one that never fails it’s the one that knows how to fail gracefully and tell you exactly why.  ( 7 min )

Python bytearray Overview bytearray is an important built-in class in Python that represents a mutable sequence of bytes. bytearray is similar to bytes, but unlike bytes, bytearray is mutable. # Create a bytearray ba = bytearray(b'Hello') print(ba) # Output: bytearray(b'Hello') print(type(ba)) # Output: ba1 = bytearray(b'Hello') print(ba1) # bytearray(b'Hello') ba2 = bytearray('Hello', 'utf-8') print(ba2) # bytearray(b'Hello') ba3 = bytearray(5) print(ba3) # bytearray(b'\x00\x00\x00\x00\x00') ba4 = bytearray([65, 66, 67, 68]) # ASCII: A, B, C, D print(ba4) # bytearray(b'ABCD') # bytes is immutable (will cause error) b = b'Hello' # b[0] = 74 # TypeError: 'bytes' object does not support item assignment # bytearray is mutable ba = bytearray(b'Hello') ba[0] = 74 # ASCII code for 'J' print(ba) # bytearray(b'Jello') ba = bytearray(b'Hello') ba.append(33) # ASCII code for '!' print(ba) # bytearray(b'Hello!') ba = bytearray(b'Hello') ba.extend(b' World') print(ba) # bytearray(b'Hello World') ba = bytearray(b'Hello') # Convert to bytes bytes_obj = bytes(ba) print(bytes_obj) # b'Hello' # Convert to string string = ba.decode('utf-8') print(string) # 'Hello'  ( 6 min )

When I interview new developers or review resumes, I keep hearing the same question: Did I pick the right first programming language? Some candidates list four languages, trying to prove they’ve explored everything. Others feel they picked the wrong one—learning Python instead of Java somehow set them back. From my experience building teams at Microsoft, Meta, and now Educative, I know that the real difference comes from what you build, not the language you start with. I’ve seen engineers start with C, JavaScript, or Python and still grow into great developers. The difference wasn’t the syntax. It was the habit of building projects, finishing them, and learning from each one. Choosing a first language is career-defining because the tech world is noisy.

The first time I opened Xcode to build an iOS app, I thought I’d have something in the App Store within a week. I had the idea, the excitement, and a “Hello, World!” running on the simulator. But then reality hit. Auto-layout was confusing, Swift’s optionals were tricky, and I had no idea how to connect UI elements to my code properly. After a week of YouTube tutorials and unfinished blog posts, my app never made it past the login screen. Years later, I gave iOS development another shot—but this time, with structure. I followed a proper course instead of scattered tutorials, and everything changed. I didn’t just understand Swift; I was building and shipping real apps.

In modern application development, it’s rare to find a single-service system. Most real-world applications rely on multiple services working together — think of a web server, database, cache, and message broker forming one cohesive stack. Managing all these containers manually can be messy. That’s where Docker Compose becomes your secret weapon. Docker Compose is a simple yet powerful tool for defining and running multi-container Docker applications. You describe your entire stack in a single docker-compose.yml file, and with one command, you can build, start, and stop everything — from your API to your database — like clockwork. Here’s why Compose is a game changer for developers and DevOps engineers alike: Simplified Configuration: Define your entire application stack in one YAML file. …  ( 9 min )

⚙️ How Cloud Computing Powers Modern Apps In today’s fast-paced digital world, apps and websites need to be fast, scalable, and always online.

AI Gone Wild: When Images Trick Machines Into Hilarious Mistakes Imagine a self-driving car mistaking a harmless yield sign for a red light, causing a traffic jam. Or a medical imaging system misdiagnosing a healthy tissue sample. These aren't glitches; they're often the result of subtly manipulated images designed to fool even the most sophisticated AI. The core concept involves crafting inputs – we'll call them "opposite attractors" – that are significantly different from typical data but still trigger the same output from a machine learning model. Instead of making tiny tweaks to an existing image to change the classification, we create entirely new images that fool the AI into seeing something familiar, even though it's visually far removed from the original object.

Create a PROMPT.md in your project root directory. Use it to store all the context necessary about your project for your agent to save yourself time from re-explaining what your project is or what your preferences and project level decisions are. Context is one of the hardest things currently when using LLMs. You're either telling the LLM what your project is in each chat, or the LLM gets lost in the sauce and forgets what it is your project is trying to accomplish, or how you're trying to accomplish it. Create a file in your project root that tells the LLM what it should know every time (you should even let the LLM write/update it also). There is a great talk by Elixir Phoenix create Chris McCord about how they are actively trying to make Elixir (and Phoenix) the best language to code with an LLM. They are mostly ensuring that it generates valid Elixir code like Enum.at(my_list, 0) instead of my_list[0] by defining Elixir syntax in a PROMPT.md file. He recommends to use that file as a base and expand on it. There's a good quote during the talk where Chris says something like: You can spend your time arguing about the morals of AI, or you can be 2-3 times more productive. You can be Michelangelo painting the Sistine Chapel, telling the assistants what broad strokes to make and do the stuff you don't want to do while you focus on the big picture and ensure the small details are right. Or you're a mangaka with assistants filling in cells, whatever. The skill of reviewing code and making sure your vision is followed becomes more important at all levels. Just because you are not hand typing every line of css, html, javascript, ruby, c++, whatever doesn't mean you aren't doing the thinking and solving the problems.  ( 6 min )

MERN Stack is a combination of four powerful technologies: MongoDB, Express, React, and Node.js. With these four tools, you can build modern, fast, and complex web applications. Let’s take a detailed look at the role of each component and what they can do together. 🗄️ MongoDB - Database: MongoDB is a NoSQL database that stores data in the form of documents. It works in a JSON-like format, which makes it very convenient to use JavaScript. You can store user lists, product catalogs, or any other type of data. Express.js is a minimalist web framework for Node.js. It simplifies server-side logic, such as routing and creating API endpoints. Express allows you to write a server quickly and in an organized manner. React is a library used for building user interfaces. It works on a component-based system, meaning you can create each part of your application separately and them combine them. This makes code reusable and easier to manage. Node.js allows you to run JavaScript code on the server. This enables the entire stack to use only one language - JavaScript - which simplifies the development process. 📱 Full-functional web applications 💼 Business applications (CRM, ERP systems) 🛒 Online stores (E-commerce) 📊 Data management systems (Dashboards) 💬 Real-time applications (Chat apps, notification systems) 🎮 Games and interactive applications With the MERN Stack, you can create powerful applications intended for the world using only JavaScript. By learning and applying this stack, you can significantly enhance your skills. 🔗 Connect: ibrohimbek.link  ( 6 min )

What Is Full-Stack Development? (A Simple Guide for Beginners) If you’ve ever heard someone say they’re a full-stack developer and wondered what that really means, you’re not alone. In simple terms, full-stack development refers to the ability to build both the front and back parts of a website or web application — everything users see and everything that runs behind the scenes. Think of it like building a house: the frontend is the design, furniture, and paint that people see, while the backend is the plumbing, wiring, and foundation that make everything work smoothly. 🖥️ Frontend: What Users See The frontend is the client side of a website — the part users interact with directly. It’s what you see when you open a web page: the layout, colors, buttons, forms, and animations. Frontend dev…  ( 7 min )

Reasoning Under a Cloud: Making Smarter AI Decisions with Fragmented Knowledge Imagine an AI trying to diagnose a patient with incomplete medical records. Or a self-driving car navigating a road where sensor data is intermittently lost. How can these systems make reliable decisions when the facts are fuzzy? The key lies in building AI that can not just process information, but also reason effectively with uncertainty. The core idea is creating a structured argumentation framework. Instead of treating arguments as black boxes, we analyze their internal structure—the premises and rules used to construct them. Then, we can model uncertainty directly within these components. This allows the system to weigh the strength of an argument based on the reliability of its foundation. Think of it li…  ( 7 min )

When it comes to software development, quality can make or break a product. But one persistent myth keeps popping up: Quality Assurance is just another word for testing. It’s easy to see why, testing is the most visible part of the process, but QA is so much more. Think of it as the entire system of practices that keeps quality top of mind from start to finish. Yes, testing is part of it, but QA includes planning, design reviews, coding standards, documentation and continuous improvements that prevent problems from ever reaching users. It’s about building quality in, not just checking for bugs at the end. For decision makers, understanding this bigger picture is key. Seeing QA as a strategic end to end approach rather than a single task is what separates average software from products that…  ( 12 min )

The emergence of advanced AI models has made it necessary to create standardized techniques for supplying them with real-time, external, or domain-specific data. A technical specification known as the Model Context Protocol (MCP) outlines the client-server communication necessary to provide this context. An MCP server, an application in charge of exposing specialized data sources like issues from Linear, design files from Figma, or repository code from GitHub, communicates with an MCP client (such as Gemini or GitHub Copilot). The LLM can perform tasks and reasoning that would be impossible with its base knowledge alone thanks to this client-server model. This fundamental feature of providing context to models was initially put forth in architectures such as Anthropic's Ask to Ask (A2A…  ( 10 min )

Modern displays are more than just LCD panels and touch sensors. Between the layers that make up your smartphone, automotive dashboard, or industrial HMI, there’s a transparent film doing critical work — the Optical Clear Adhesive (OCA). This adhesive is the reason screens stay bright, responsive, and durable even in challenging conditions. In this article, we’ll explore what OCA is, why it’s used, and how it’s changing display manufacturing. OCA is a transparent adhesive film used to bond optical layers together — such as the cover glass, touch panel, and display module. Unlike liquid adhesives, OCA comes as a pre-cast solid sheet. During assembly, it’s applied under pressure and temperature to create a bubble-free optical interface between components. In simple terms: OCA replaces th…  ( 8 min )

Introduction. The Beating Heart of Intelligent, Autonomous AI Agents If you’ve ever written a for or while loop in programming, you already understand the core idea behind the Agent Loop. It’s a cycle a repeating process that continues until a condition is met. But when it comes to AI agents, this loop becomes much more powerful. It’s not just about iteration; it’s about reasoning, tool use, and autonomous decision-making. In the AWS Strands Agentic Framework, the Agent Loop is the engine that powers intelligent behavior. It continuously processes input, reasons through possible actions, calls tools, and generates responses all while maintaining context and adapting to new information. This post dives deep into how this loop works, its key components, and why it’s at the heart of model…  ( 9 min )

Introduction Random testing can explore broad state spaces but often leaves gaps. Directed tests provide structure but risk missing unexpected interactions. The most effective approach combines the two: constrained-random stimulus for breadth and directed suites for precision [2]. The Challenge: Random Alone Is Not Enough Directed suites can systematically validate those features, but cannot anticipate subtle corner cases. Together, these limitations highlight the need for a combined strategy. Random stimulus is used to discover the unexpected, while directed suites guarantee compliance with the specification [3]. Note that compliance is a necessary but not sufficient measure for verification. Constrained-Random Testing with STING Constrained-random test generation is often the starting po…  ( 11 min )

In the previous article, we introduced a PostgreSQL database to our forum, achieving persistent data storage, so that data is no longer lost even if the server restarts. Now we can confidently make more improvements. However, you may have noticed that all of our current interface styles (HTML) are written directly in main.py. Does this mean that for every new feature in the future, we have to stuff more HTML into main.py? This is not only troublesome to write, but it also leads to a large number of HTML strings being mixed into the Python code, making the code difficult to read and maintain. To solve this problem, this article will introduce the Jinja2 template engine to separate the backend logic (Python) from the frontend presentation (HTML), making the project structure clearer and easi…  ( 9 min )

May Habib, co-founder and CEO of Writer AI, delivered one of the bluntest assessments of corporate AI failures at the TED AI conference on Tuesday, revealing that nearly half of Fortune 500 executives believe artificial intelligence is actively damaging their organizations — and placing the blame squarely on leadership's shoulders. The problem, according to Habib, isn't the technology. It's that business leaders are making a category error, treating AI transformation like previous technology rollouts and delegating it to IT departments. This approach, she warned, has led to "billions of dollars spent on AI initiatives that are going nowhere." "Earlier this year, we did a survey of 800 Fortune 500 C-suite executives," Habib told the audience of Silicon Valley executives and investors. "42% …

In a striking act of self-critique, one of the architects of the transformer technology that powers ChatGPT, Claude, and virtually every major AI system told an audience of industry leaders this week that artificial intelligence research has become dangerously narrow — and that he's moving on from his own creation. Llion Jones, who co-authored the seminal 2017 paper "Attention Is All You Need" and even coined the name "transformer," delivered an unusually candid assessment at the TED AI conference in San Francisco on Tuesday: Despite unprecedented investment and talent flooding into AI, the field has calcified around a single architectural approach, potentially blinding researchers to the next major breakthrough. "Despite the fact that there's never been so much interest and resources and …

One of the leading architects of the current generative AI boom — Microsoft CEO Satya Nadella, famed for having the software giant take an early investment in OpenAI (and later saying he was "good for my $80 billion") — published his latest annual letter yesterday on LinkedIn (a Microsoft subsidiary), and it's chock full of interesting ideas about the near-term future that enterprise technical decision makers would do well to pay attention to, as it could aid in their own planning and tech stack development. In a companion post on X, Nadella wrote, “AI is radically changing every layer of the tech stack, and we’re changing with it." The full letter reinforces that message: Microsoft sees itself not just participating in the AI revolution, but shaping its infrastructure, security, tooling …

If you've heard the folk tale of John Henry, you know the story: a steel-driving man who raced against a steam-powered hammer to prove human worth and dignity. He won the race but died with his hammer in his hand. It's a powerful allegory about technological change, human pride, and the cost of resistance. Today, as AI coding assistants become ubiquitous in software development, many developers feel like they're staring down their own steam-powered hammer. The anxiety is real—will AI replace us? Should we resist? Are we racing toward obsolescence? But here's what the John Henry story often obscures: the steam engine didn't eliminate workers; it transformed work itself. The railroad industry exploded after mechanization. More tunnels were built, more tracks laid, more infrastructure created…  ( 16 min )

There is a quiet moment, just after a feature is "done," when you click a link and witness the browser's brutal ritual. The entire page—the meticulously crafted header, the complex sidebar, the persistent player—blinks out of existence. For a heart-stopping second, there is nothing. Then, it all rushes back, reassembling itself just to update a small counter in the corner. We've accepted this as the cost of doing business on the web. Our server renders a complete, holistic page, a single, indivisible block of HTML. But our users don't experience the page as a monolith. They experience it as a collection of independent components: a shopping cart, a live feed, a search result list. What if our technology reflected that reality?

Speaking of coding, I got a demo started but ran into a road block. The good news, I think I know a way to get around it. Personal : Did a bunch of sketching and design for some stickers. I did some measurements and modified a model. I also went through some projects on Bandcamp that I plan to pick up this week. I thought of another prototype that I want to make to show the prospective client. Been thinking and researching the best way to be able to print it reliably. I'm thinking I may go back and put in a little bit of time in the demo I was building for work. I think a couple of hours tonight will save me a bunch of time tomorrow because I won't have meetings or people asking me questions and I'll be able to focus. Like I said, I think I have an idea of what I need to do to be able to get it to a good place to be able to demonstrate the idea. Yeah, I'll work on that and get back to putting together the social media posts for the Bandcamp projects and think and sketch more the prototype and stickers. It's getting dark, going to eat dinner and get to work. Have a great night! peace piece https://dwane.io / https://HIPHOPandCODE.com  ( 6 min )

There’s a moment in every seasoned Rails developer’s journey when the app/models directory stops feeling like a well-organized toolbox and starts to resemble a junk drawer. You know the one. It’s where the User model, a proud and complex entity, lives next to a ReportGenerator concern, a PaymentService class, and a NotificationsHelper that’s seen things. We started with a beautiful, coherent BlogPost model. Then came FeaturedBlogPost. Then SponsoredBlogPost. Then the BlogPost::ExportToNewsletter service object. Our once-simple domain has become a tangled web. We’ve been building a Monolith, and without a map, we’re getting lost in our own city. It’s time to become cartographers. This isn't a story about microservices or complex architecture. This is the story of bringing order to the monol…  ( 9 min )

You’ve just been assigned to The Monolith. It’s not a pejorative; it’s a title earned through years of service. This Node.js codebase is the bedrock of your company—a sprawling, complex entity with layers of history etched into its very structure. You git clone, run npm install, and are greeted not by errors, but by a different kind of challenge: the weight of legacy. In the heart of this digital forest, you find trails overgrown with tangled functions, campsites littered with // TODO comments, and ancient, runic code that everyone is afraid to touch. The pressure is always to build the new feature, to hack in the hotfix. But you know that unmanaged entropy is a technical death sentence. This is where we embrace a different philosophy. Not a grand rewrite, not a paralyzing freeze, but a ge…  ( 10 min )

Building Streaky: A GitHub Streak Guardian Part 1: The Journey from "Simple App" to Distributed System I thought building a GitHub streak reminder would take a weekend. It took 3 weeks and taught me more about distributed systems than any tutorial. The "simple" idea: Check users' GitHub contributions daily Send Discord/Telegram notification if they haven't committed That's it What actually happened: 5 failed attempts, CPU limits, IP blocking, race conditions, and a complete architecture redesign. I kept losing my GitHub streak because I'd forget to commit on busy days. Existing solutions were either: Self-hosted (requires always-on server) Paid services Missing Discord/Telegram integration So I decided to build my own. How hard could it be? The naive approach: export async fun…  ( 10 min )

I saw the original Isotope Javascript fancyness and I just had to write a rebuild using modern web standards. Check out my rebuild! My version of Isotope uses a grid layout and animates using view transition. It is silky smooth, blazing fast and has graceful degredation. The code consists of only 63 lines of vanilla JS, while the old version required an astonishing 3500+ lines. If you choose to leave the sorting out, you can even reduce the code to 37 lines. Yup... the web has come a long way. Just set id="isotope" on any container and give its children classes that represent categories, like class="metal". Then create some buttons with data attributes, like data-filter=".metal" or data-sortby="symbol". Load the JS from the demo in the footer and it works. You don't need ANY of the CSS. That is all just fancy stuff. Note that my version only supports basic filtering and sorting (which are the only things I ever used from the original code). Also note that the animations do not work in Firefox (yet). Finally, be aware that you can not use this Isotope filter twice on the same page, as it lacks abstraction for that.  ( 6 min )

I’ve been working on my React project today and focused on handling forms properly. I combined React Hook Form, Zod validation, and EmailJS to create a real working contact form that actually sends emails. Step 1: Setting up React Hook Form + Zod npm install react-hook-form zod @hookform/resolvers sonner Then, I imported everything in my ContactForm.jsx file: import { useForm } from "react-hook-form"; import { zodResolver } from "@hookform/resolvers/zod"; import * as z from "zod"; import { toast } from "sonner"; I created a simple validation schema using Zod: const contactSchema = z.object({ name: z.string().min(1, "Name is required").max(100), email: z.string().email("Invalid email").max(50), message: z.string().min(1, "Message is required").max(1000), }); Zod lets you describe …  ( 8 min )

You stand before the loom of your application, a Senior Developer, a master of the craft. You've honed your Node.js to a fine edge. Your REST APIs are elegant, your service logic is pristine, and your unit tests are a suite of gleaming, isolated sculptures. They are beautiful, but they are individual pieces. They don't tell you if the tapestry, when woven together, will hold. The database layer is that tapestry. It's the interconnected weave of data, relationships, and state that can make or break your application. Unit tests mock the database, admiring the loom from a distance. But an artisan must touch the threads. This is a journey into the heart of that tapestry: Integration Testing the Database Layer. It's not just writing code; it's the art of creating a resilient, predictable, and t…  ( 10 min )

⚠️ Warning: The "Overfitting to a Single Data Point" Pitfall In AI-powered media analysis, it's easy to fall into the trap of overemphasizing a single data point that may not be representative of the larger trend or dataset. This phenomenon is known as "overfitting to a single data point." It occurs when a model is heavily influenced by an outlier or an unusual observation, leading to inaccurate conclusions and flawed insights. For instance, consider a media analysis project where a model is trained to predict the sentiment of social media posts about a particular brand. If the dataset contains a single post with an extremely positive sentiment, the model may learn to associate the brand with an overly optimistic tone. However, this might not reflect the actual sentiment of the majority of the users, potentially leading to a biased perception of the brand's reputation. To avoid this pitfall, data scientists and media analysts must employ robust methods to validate their findings.... This post was originally shared as an AI/ML insight.

If you’ve been working with APIs for a while, you’ve probably bumped into Postman. Maybe you even used it once or twice and thought, “Okay, nice little GUI for cURL.” That’s what most people think at first. I did too. But here’s the truth: Postman isn’t just a fancy interface to send GET or POST requests. It’s an entire development environment built around how real teams actually design, test, and debug APIs. Once you understand what it can do, it’s hard to imagine building or maintaining APIs without it. Let’s go step by step—through what I like to call the “levels” of Postman use. Most developers start here. The “Request Builder” is where you replace ugly, quote-filled terminal commands with a clean, structured interface.

Binary Hardening in Rust (and Beyond) Hello stranger of the internet, and welcome back! Rust developers have access to powerful binary hardening techniques that make reverse engineering significantly harder—from compile-time string encryption and control flow obfuscation to self-integrity checks and memory protection. These aren't theoretical concepts: they're practical strategies that raise the cost of tampering and credential extraction in production software. Binary protection isn't just paranoia, or maybe is... Every application that ships to untrusted environments—whether compiled binaries, bytecode, or bundled JavaScript—needs defenses against tampering, credential extraction, and reverse engineering. The difference between "some kid on Reddit cracked my app in 3 hours" and "determ…  ( 10 min )

Over my career, I’ve had the chance to build a wide variety of web applications — from small startups to core, high-traffic products for some of the largest tech companies in the country. This is actually my first article ever and honestly, not the easiest topic to start with. But let’s see how it goes. I want to start a series of articles on a topic that has been on my mind a lot in recent years — frontend application architecture. Actually, this isn’t just about frontend — many of the ideas apply to software in general, regardless of language or platform. But since my experience is mainly in frontend, that’s the perspective I’ll focus on. Much of this will also apply to backend applicati…  ( 7 min )

Article Short Review Meta‑Awareness Enhancement in Large Language Models The article investigates the meta‑awareness of reasoning models—how language systems internally gauge their own problem‑solving processes. By demonstrating a pronounced misalignment between predicted meta‑information and actual rollouts, the authors argue that current large language models lack true self‑knowledge. To address this gap, they introduce Meta‑Awareness via Self‑Alignment (MASA), a training pipeline that leverages self‑generated signals rather than external datasets. MASA incorporates two efficiency strategies: filtering out zero‑variance prompts and truncating unlikely rollouts, thereby reducing computational overhead. Experimental results show significant accuracy improvements across in‑doma…  ( 8 min )

For a long time, “protein” was almost synonymous with chicken, eggs, and whey shakes. But today, more people are realizing that you can build muscle, stay energetic, and maintain great health entirely on vegetarian or plant-based foods — as long as you know where to get your protein and how to balance it. Whether you’re vegetarian for health, environmental, or ethical reasons, this guide will show you how to meet your protein needs naturally. Why Protein Matters Protein isn’t just for bodybuilders. It’s the foundation of every cell in your body — from muscles and bones to skin, enzymes, and hormones. It repairs tissues, supports immunity, and fuels metabolism. The average adult needs roughly 0.8–1.0 grams of protein per kilogram of body weight daily, but those who lift weights or play spor…  ( 8 min )

You publish an article. It gets some views. Maybe a few reactions. But then what? DEV.to's built-in analytics show you the basics, but they don't answer the questions that actually matter: Which tags are driving the most traffic? Is my content getting better over time? Which old articles should I update? What's my actual engagement rate? Should I be using different tags? After publishing 16 articles and hitting 983 views, I realized I was flying blind. So I built DEV.to Analytics Pro - and the insights completely changed my content strategy.

Nowadays, when a user visits our website or web application using a mobile, tablet, or laptop — he should be able to use it comfortably. This is the main purpose of responsive web design. Responsive design means the layout, text, images, buttons, etc. will adjust automatically according to the screen size. 1. Mobile-First Approach We have to start our design with small screens like mobile. Then, gradually, we can expand the design for larger screens. 2. Viewport Meta Tag Usage In the tag of HTML, the viewport meta tag is required. The code looks like this: It helps the website become responsive according to the device’s viewport. 3. Using Max-Width for Layout Control and Center Alignment On large screens, the website content should not be too wide horizontally, and on small screens, it should fit properly and look good. .container { max-width: 1200px; margin: 0 auto; padding: 0 20px; } Every modern website uses this technique. 4. Relative Units and Flexible Layout We should use %, rem, or em instead of pixels. .container { width: 90%; } 5. Using Flexbox and Grid Layout In the past, people used float-based layouts, but nowadays, the simplest and most modern solution is using Flexbox and Grid. 6. Making Images and Videos Fluid We have to use relative units and avoid fixed pixel sizes for images. img { max-width: 100%; height: auto; } 7. Responsive Typography If the screen is small, font sizes should also be smaller; otherwise, they will look oversized. 8. Responsive Navigation Menu The navigation bar is one of the most important parts of a website. We can use media queries for small screens and convert the menu layout into a vertical one. Responsive web design is now a mandatory part of modern web development. If we can properly use HTML, CSS, Flexbox, Grid, and Media Queries, we can build websites that work smoothly and beautifully across all screen sizes.  ( 8 min )

Example: public class Person { private String name; // Constructor public Person(String name) { this.name = name; } } Constructors are called when you create an object: Person person = new Person("Gaurav"); A default constructor is a no-argument constructor that Java automatically adds if you do not define any constructor in your class. Example: public class Employee { private int id; private String name; } The Java compiler automatically adds: public Employee() { super(); // calls Object class constructor } So you can still do: Employee e = new Employee(); // ✅ Works fine If you explicitly define any constructor (parameterized or no…  ( 9 min )

Sean and Amanda pick up their yearlong countdown at #8 with Bong Joon-ho’s Parasite, a film they say delivers one of the most jaw-dropping endings ever. They dig into its razor-sharp portrait of class systems and how every little choice—framing, sound, set design—amplifies the movie’s themes. They also toast Parasite’s history-making Best Picture win, noting how that Oscar moment flipped the Academy script and cemented the film’s place as a modern classic. Watch on YouTube  ( 6 min )

I built a minimal Spring Boot service for my HNG Stage‑0 backend task that returns a profile object plus a fun cat fact. The goal was to deliver a clear, runnable microservice in a few files so reviewers can quickly run and inspect the code. What it does Exposes GET /me Returns a JSON payload with status, a small user profile (name, role, links), a timestamp, and a cat fact fetched from https://catfact.ninja/fact Architecture (short) ProfileController — handles /me and returns a ProfileResponse DTO. ProfileService — builds the profile and fetches the external cat fact using Java HttpClient. Profile (domain) and ProfileResponse (DTO) — simple POJOs for shape and serialization. Spring Boot entrypoint and a single minimal unit test to ensure application context loads. Why this shape? Minimal surface area: reviewers can audit the domain, controller, and service quickly. External call isolated in the service so it’s easy to mock or replace. Small codebase is ideal for early-stage tasks and focused feedback. How to run locally From the project root (uses the included Maven wrapper): ./mvnw spring-boot:run Then open: http://localhost:8080/me What I learned / next steps Keep services focused and small for fast review cycles. Inject HttpClient (or a wrapper) to make the external API call testable and mockable. Add structured error handling and logging for robustness. Add unit tests that mock the cat-fact API and an integration test for the controller. check the repository: here  ( 6 min )

On October 20, 2025, one of AWS’s largest data centers in Virginia went dark. A DNS failure during a DynamoDB API update cascaded into a massive global outage, crippling over a thousand services - from banking apps to crypto networks like Coinbase, Base, and Infura. It was another reminder that almost everything online, even “decentralized apps,” still runs on someone else’s computer.​ AWS had become the beating heart of global infrastructure. So, when it stumbled, the internet staggered. But what truly caught the crypto industry’s attention wasn’t that Coinbase or OpenAI went dark - it was that Ethereum access through Infura also went down.​ That led to an uncomfortable question: if blockchain is supposed to be decentralized, why does a bug in one AWS region bring half of Web3 to its knee…  ( 9 min )

Learnings from the recent AWS failure. It started with confusion. At 7:40 AM BST on October 20, 2025, a Monday morning like any other, people around the world reached for their phones and found... nothing. Duolingo wouldn't load—goodbye, 500-day streak. Snapchat refused to open. Ring doorbells went blind. Wordle players stared at blank screens, their morning ritual interrupted. Coinbase users couldn't check their crypto portfolios. Even Amazon's own shopping site was struggling. On Twitter (somehow still working), the complaints began flooding in. "Is it just me or is everything down?" Thousands asked the same question simultaneously. Within minutes, Downdetector lit up like a Christmas tree—over 50,000 reports cascaded across services that seemingly had nothing in common. Banking apps, da…  ( 14 min )

Hi everyone, I'm facing a lot of issues — there are many models, many open-source ones, and many others that are quite costly — but none can guarantee that 100% (or even close) of the data will be extracted correctly from my PDFs, DOCX files, or other formats. I also have another problem: I'm Italian and want to build this for an Italian audience, so the documents will be in Italian — and some extractors don’t handle that very well. So my question is: what kinds of systems, tools, or approaches do you use to extract all the information from your documents before the chunking and embedding phase? Let me know, thanks!  ( 6 min )

I get that desktop applications are out of style these days. But they are still a good way to deliver powerful features and high performance graphics. However, delivering modular Java applications on Windows is a challenge. It almost seems like Java and Windows have conspired against each other. Java requires that all module jars are listed in one command line parameter. That works fine when Unix shells have a >100K character command line. Windows batch files have a relatively short limit (8191) on the lengths of their command lines. This makes it impossible to launch large-ish modular Java applications on Windows using the standard scripting model of every parameter on the JVM’s launch command line. The work around is to specify an argument file (e.g. @app.args) when launching Java.…  ( 10 min )

We debate its risks, celebrate its breakthroughs, and wrestle with its implications. But amid this vibrant discourse, a darker current persists: not from cautious skeptics or the indifferent, but from a subset of individuals who seem almost viscerally repelled by AI’s very existence.

I’ve been doing the job hunt all wrong. Like many of you, I’ve been on the hunt for a few months now and it can be exhausting. Sending application after application and hearing nothing back is demoralizing. A few weeks ago, I attended the Commit Your Code tech conference in Frisco, TX, and it truly changed everything for me. I met an incredible community of developers helping each other learn, grow, and navigate today’s job market, especially through the 100Devs and CYC Discords. I’ve been in the industry for over six years, but the most important thing I’ve learned recently wasn’t technical — it was personal. Back in 2021, when dev demand was at an all time high, I was spoiled. I didn’t have to apply for jobs. A friend made an intro, I interviewed, and BOOM, hired immediately. For better or worse, that market’s gone now, and for a while, I was still acting like it wasn’t. I’ve had to accept that I can’t take employability for granted anymore. The game has changed. I need to be proactive in new ways: by networking intentionally, building real connections, and creating a visible online presence. This shift hasn’t exactly been intuitive for me. Funny enough, we’re expected to pivot constantly on the job, by learning new stacks and new systems; when it comes to our own careers, that same adaptability can be hard to find. But here’s the thing: problem-solving is what we do. So if you’re out there grinding, wondering if it’s still possible, know that I think it is. Rethink your strategy. Build proof. Connect with people who are learning and sharing too. It’s not easy work, but it beats sending 1,000 applications into the void. You’ve got this. 👊  ( 7 min )

It is well known that software development is a lifelong learning process. At the start of my career, most of my early interactions involved SQL databases. I used many SQL administrative tools, such as DBeaver, SQLiteStudio, and MySQL Workbench. When I first began working with DynamoDB, I didn’t realise early enough that I needed a mindset shift, and I am sure quite a few developers fell into a similar trap. In designing my DynamoDB table structure, I treated queries and access patterns as afterthoughts and focused more on mappings and relationships between items and entities, just as I would with a relational database. Persistently applying these old SQL habits often led me to deal with inefficient scans, which was deeply frustrating. When working with DynamoDB, you need to shift your min…  ( 9 min )

Hey everyone!!! Tihar is here in Nepal 🎉. With the holiday break on, I decided to wrap up another portfolio project: designing and deploying a complete, event-driven e-commerce order processing system on AWS. I’ve previously built a few monolithic REST APIs, but this time I wanted to challenge myself and understand how microservices differ from monolithic systems in practice. So I chose a microservices architecture centered around an Event Bus (Amazon EventBridge). While the project follows a microservices pattern, my main goal wasn’t to build a fancy UI or user-facing backend — instead, I focused on AWS architecture, infrastructure, and operational maturity. To push myself deeper into the IaC world, I decided to deploy everything using raw CloudFormation YAML — no SAM, no CDK, no Terr…  ( 10 min )

Changing Password Supabase provides a built-in functionality for resetting passwords via a link. However, if you want to change your password while logged in, there is no built-in functionality for this scenario. To handle this, you can use a custom function on Supabase. Run the following code in your Supabase SQL Editor: create or replace function changepassword("current_plain_password" text, "new_plain_password" text, "current_id" uuid) returns varchar language plpgsql security definer as $$ DECLARE encpass auth.users.encrypted_password%type; BEGIN SELECT encrypted_password FROM auth.users INTO encpass WHERE id = current_id and encrypted_password = crypt(current_plain_password, auth.users.encrypted_password); -- Check the currect password and update IF NOT FOUND THEN return 'incorrect'; else UPDATE auth.users SET encrypted_password = crypt(new_plain_password, gen_salt('bf')) WHERE id = current_id; return 'success'; END IF; END; $$ This will create a custom function that you can call from any platform. Here’s the syntax for Javascript: const { data, error } = await supabase.rpc('changepassword', { current_plain_password: oldPassword, new_plain_password: newPassword, current_id: currentUserId }); Here- current_plain_password is the old password new_plain_password is the new password current_id is the id in the current session of the app. Logging Out from Active Sessions on Other Browsers/Devices To sign out from all active sessions, you can use the following commands: // defaults to the global scope await supabase.auth.signOut() // sign out from the current session only await supabase.auth.signOut({ scope: 'local' }) // sign out from the other session without the current await supabase.auth.signOut({ scope: 'others' }) Upon sign out, all refresh tokens and potentially other database objects related to the affected sessions are destroyed and the client library removes the session stored in the local storage medium.  ( 7 min )

DevOps is more than a role; it's a culture and mindset that bridges the gap between development and operations. Any member of an IT organization or software company can embrace DevOps principles to improve collaboration, streamline processes, and enhance software delivery.

Nobody wants to build things from scratch. That’s why APIs exist. So I took the time to find 11 underrated, practical APIs you can plug into your projects and start building right away. You will be able to scrape web pages, access threat levels of websites, get real time foreign exchange rates, stock data, track global flights, check violent images, fetch Google search results and much more. Let's jump in. IPStack API - real-time IP geolocation and accessing threat level This is one of the most valuable ones on the list. IPstack provides a powerful, real-time IP to geolocation API capable of looking up accurate location data and assessing security threats whether they are from risky IP addresses (which need to be dealt with). Features: Lookup country, region, city, timezone, currency, c…  ( 16 min )

Everything Wrong With M3GAN 2.0 is a new CinemaSins video that tears into the sequel’s pacing and plot, ultimately declaring that the killer doll is way less exciting this time around. Expect the usual sarcastic riffs, nitpicks, and “sins” against everything from character logic to special effects. The description also plugs the CinemaSins site, social channels, and a quick poll, plus invites support on Patreon. You’ll find links to their Discord and Reddit communities, a shout-out to the writers, and all the usual CinemaSins social media handles for more movie-mocking content. Watch on YouTube  ( 6 min )

TL;DR In the latest Caravan of Garbage roundup, the hosts finally tackle the two live-action Alien vs Predator movies—2004’s Alien vs Predator and 2007’s Requiem. After years of teasing a shared universe in comics, games and even Predator 2, these films deliver a few cool moments but mostly underwhelm compared to the hype. Next week, they’ll pivot to the first four Predator movies. Meanwhile, you can hop over to bigsandwich.co for early access videos, bonus podcasts and more, or follow James and Maso on Twitter to keep up with all the monster-mashing mayhem.

Hi everyone! 👋 I’m the developer behind a little project called PleaseRSVP.ai — a simple tool that helps parents create beautiful AI-generated birthday invitations in under a minute. 🎂✨ The idea came from my own struggle as a parent — every year, I’d spend hours trying to design a nice invite for my kid’s party. Between juggling work and family, I wanted something that looked great but didn’t take forever to make. So… I built it! You enter your child’s name, age, date, and location — and the system instantly creates a themed invitation with a built-in RSVP page. Right now, new users can generate one invitation for free — no signup hassles, no limits. If you have a few minutes to try it, I’d really love your honest feedback or suggestions! ❤️ Thanks so much! — Ned  ( 6 min )

I have wanted to write about tech conferences for a while, and last week I was at Codemotion in Milan. Perfect excuse to finally do it. If you follow me here you know I usually share tutorials and technical content, but there is another huge part of our craft that I discovered only a few years ago: conferences. They open new opportunities and new ways of thinking that you will miss if you only focus on the tech. That would be a shame. While I am still wearing the conference badge, here is why I think you should go to large tech events, what to expect, the pros, and yes, the cons. This article is actually an edited version of me rambling for ten minutes, you can watch it here: Meet people The biggest advantage is simple: meet people.

Recently, our People & Culture team shared something in our Learning Nuggets Slack channel: “The Four Tendencies” quiz, a framework by Gretchen Rubin that explores how people respond to expectations. The premise is straightforward: we all face external expectations (from others) and internal expectations (from ourselves). The way we respond to these defines which of the four tendencies we belong to: “I do what others expect of me—and what I expect from myself.” They meet both outer and inner expectations with discipline and consistency. Their motto: “Discipline is my freedom.” “I do what I have to do. I don’t want to let others down, but I may let myself down.” They readily meet outer expectations but struggle with self-imposed ones. “I do what I think is best, according to my judgment.

We gave an AI Coding Assistant a design file. Here is what happened. AI is changing everything - including how we build software. Coding assistants are everywhere, and the hype is real. But so are the concerns: Will it scale? Can I trust the output? What happens when things go wrong? We get it. We are a software company ourselves and like everyone else: we are under pressure to deliver more, faster and smarter. So we asked us a simple question: what if we could make AI coding assistants "safe by design"? In our product, architecture and design are not an afterthoughts. They are executable assets packaged as living design files that define: what gets built, how it works and why it matters. So we took a coding assistant - in this case, the choice fell on Cursor - to run a hackathon. We didn’t write user stories. We didn’t hand over vague requirements. Instead, we fed the coding assistant the structured design artifacts generated from the knowis Workbench. Simple. The Result? It worked well: Code generation was fast, focused, and aligned with our intent. Architecture guardrails stayed intact, even with rapid iterations. Review and testing? Easier than ever. Shifting the (investment) focus to the "left" of the software development process doesn’t just mean testing earlier. It means thinking, designing earlier. Better. Because AI accelerates code but architecture and design defines what gets built. In a few words: you don’t need to fear coding assistants. You need to feed them better inputs.

Understanding LangGraph: Building Smarter, Stateful AI Workflows LangGraph has recently become one of my favorite tools from the LangChain ecosystem — and for good reason. If you’ve ever found yourself struggling to manage multi-step AI reasoning, dynamic state, or complex tool orchestration, LangGraph feels like that missing link in the chain(insert pun here). So what is LangGraph and when you should use it instead of standard LangChain, and some of its most exciting features like reducers, super-steps, memory checkpointing, and even a bit of time travel. LangGraph is an extension of LangChain designed for stateful, graph-based AI applications. Think of it like this: LangChain lets you build chains (step-by-step sequences). graphs — dynamic, branching workflows where each node can make …  ( 8 min )

Notion recently announced custom AI agents, but theirs only run inside Notion. We have been building Rowboat, an open source platform for self-hosted, cross-tool, collaborative AI agents. Rowboat ships with native MCP support as well as 500+ built-in product integrations. 👉 GitHub: https://github.com/rowboatlabs/rowboat 👉 Demo: https://youtu.be/KZTP4xZM2DY Work rarely lives inside one app. Email, docs, knowledge bases, internal APIs, and research sources all sit in different places. Combining these for complex real-world use cases is precisely why multi-agent orchestration is required. We want agents that can: ✅ Run on your own infrastructure. Feature Notion Custom Agents Rowboat (OSS) Self-hosted / local runtime No Yes Multi-agent orchestration Limited Yes Extensible through MCP Yes Yes Native RAG (docs and URLs) Limited Yes Support local models No Yes Inspectable prompts and flow No Yes We think of agentic systems as a spectrum. Side of spectrum Useful for Deterministic pipelines with a fixed LLM call order Repeatable workflows Fully agentic orchestration Assistants that decide how to act Splitting responsibilities across multiple agents reduces context pollution, makes each unit testable, and mirrors how real teams work. We ship tested agent patterns such as manager and worker roles, internal task agents, and pipelines. This avoids visual flowchart builders that become unwieldy once the system grows.

My two kids are quite different. The younger one is our chatterbox while the older one barely shares a thing. "How was school? Fine." At 'circle time' in school, every kid is supposed to go around sharing one thing that makes their heart happy. My kid has 'passed' every.single.time. for over a year! Needless to say, this has been a delicate balance in our household of trying to get more but not be pushy about it so we create a safe space. Well, we had a breakthrough over the weekend! We hosted friends for a few nights and got to witness one of their family rituals - "highs and lows". Every night, this family shares one high and one low they experienced during the day. Usually done over dinner but if they can't all be present, right before bed time. I think one of the keys is that everyone is involved. Level the playing field. They invited us to do it with them one night and I was sure my kid would pass as she scrambled to hide behind my partner and look away from everyone waiting for a response. To my utter shock, she participated! Enthusiastically. My partner and I were shocked, and decided this was something we would need to try again. And we have, and it's worked! She will thoughtfully reflect on her day and pull out something that made her happy, and something she was less than pleased about. It's not a super long conversation but it feels special that it's coming honestly from her as opposed to a response to some sort of interrogation by us. I'm hoping this can be a new daily routine...forever? If we can bake it in as just how our family functions, I hope we can hold it through the teenage years and beyond. Anyway, just wanted to share! I know there are a million tricks out there so this is just one of many you could try if you have a quiet kid too.  ( 8 min )

Εισαγωγή — Τι είναι το JWT (JSON Web Token) Το JWT (JSON Web Token) είναι ένα compact, URL-safe φορμάτ για να μεταφέρεις αξιώσεις (claims) ανάμεσα σε κόμβους (client ⇄ server). Ένα τυπικό JWT αποτελείται από τρία μέρη, χωρισμένα με τελείες: Ένα JWT έχει αυτή τη μορφή: xxxxx.yyyyy.zzzzz xxxxx → Header (π.χ. τύπος + αλγόριθμος υπογραφής) yyyyy → Payload (τα claims) zzzzz → Signature (η ψηφιακή υπογραφή) 1. Header — περιγράφει τον αλγόριθμο υπογραφής και το τύπο, π.χ. { "alg": "HS256", "typ": "JWT" }. 2. Payload — JSON με claims (π.χ. sub, exp, iat, roles, custom claims). Αυτό το κομμάτι — το “Payload” μέσα στο JWT — είναι ουσιαστικά η καρδιά του token, εκεί που αποθηκεύονται οι πληροφορίες (claims) για τον χρήστη ή τη συνεδρία.

Sí, he encontrado el lenguaje de programación perfecto. Ni C# ni Python, que son los que he estado empleando hasta este momento, son capaces de cubrir mis necesidades como puede hacerlo GulfOfMexico. Merece la pena echarle un vistazo. ¿Booleanos true/false? Eso es demasiado limitante. Los booleanos pueden tener tres valores: true, false y maybe. Hay verdaderas constantes. ¡Solo márcalas insistentemente con const! Por cierto, sí, el final de instrucción es la exclamación ('!'). const const const pi = 3.14! ¿Listas que empiezan en 0 (como C), o en 1 (como en Basic)? ¡Mejor en -1! Por cierto... ¡Por fin! ...puedes acceder a posiciones con números reales, en coma flotante. const var scores = [3, 2, 5]! scores[0.5] = 4! // 3, 2, 4, 5 Los operadores past y previous permiten consultar el pasado... y el futuro. const var score = 5! score++! print(score)! //6 print(previous score)! //5 print(next score)! //7 ¿Tu código solo fluye de arriba a abajo? ¡Estás obsoleto! Déjame presentarte la instrucción reverse. Buena parte de esta flexibilidad es la posibilidad de sobrecargar variables. const const message = "Hello"! print(message)! const const message = "world"! reverse! Además, hay que tener en cuenta que la palabra clave function cuenta con todos los alias resultantes de eliminar letras (en orden) de esta palabra clave: fi bonacci (n) => { const var sum = 1! const var i = 0! when (i < n) { sum += sum + previous sum! i++! } } Por no mencionar el operador delete, que permite eliminar aquellos elementos que nos estorben. delete null! // El error del millón de dólares delete 13! print(12 + 1)! // Error! ¿A qué esperas? ¡Adelante, instálalo y disfrútalo! Eso sí, ten en cuenta que es necesario instalarlo a través de su instalador. A su vez, el instalador debe instalarse mediante el instalador del instalador.  ( 7 min )

LLMs as Data Mines: Unearthing Gold from 'Thought' Circuits Ever felt like you're drowning in data, but still struggling to find the right examples to train your AI? You're not alone. Feeding your large language model (LLM) the perfect diet is key to unlocking its full potential, but sifting through mountains of information is a real bottleneck. What if the LLM itself held the secret to curating that ideal dataset? The core idea is simple: LLMs, when tackling complex tasks like math problems, activate specific, interconnected groups of 'neurons' – think of them as dedicated 'thinking' circuits. We can measure how strongly different data points activate these critical circuits within the LLM. The data that lights up these circuits the most intensely is, unsurprisingly, the most relevant a…  ( 7 min )

We significanly reduced the incidence of these fails by specifying a clear option like this: config.before(:each, :js) do Capybara.default_set_options = { clear: :backspace } end  ( 6 min )

AI agents are becoming more powerful every day. They can chat, write code, answer questions, and help with tasks that once required human reasoning. They all share one challenge: how to handle knowledge/context over time. Two architectural patterns have emerged to fill this gap: Retrieval-Augmented Generation (RAG) and Memory. Both aim to make large language models (LLMs) more capable, context-aware, and cost-efficient. Yet they solve different problems and fit different stages of an agent’s lifecycle. In this article, we’ll explore both in simple terms, show how they differ, and explain when to use each, or both together. LLMs are stateless by design. Each prompt is processed independently; once you send a new request, the model forgets everything that happened before unless you include i…  ( 10 min )

How document-driven structure transforms stateless AI assistance into continuous, auditable engineering You're in your fifth AI session today. The code is flowing faster than you've ever experienced. Then you ask the AI to integrate yesterday's work—and it has no idea what you're talking about. This is the paradox of modern AI-assisted development: your code appears faster than ever, but your project feels more fragile. Research from GitHub, IBM, and METR documents what developers are experiencing: AI excels at generation but struggles with integration. In isolated sessions, output is fast and often high-quality. Across multiple sessions, coherence breaks down. Context vanishes. An AI might write a perfect authentication handler today, then suggest changes tomorrow that silently break it. …  ( 17 min )

I recently spent 3 hours debugging a simple config file parser. What should have been a 5-minute task turned into a nightmare of BufferedReader, try-with-resources, charset issues, error handling, and manual backup management. I realized Java's file I/O is scattered and outdated. That's why I built OpenLoom, a modern, zero-dependency Java library that unifies reading, writing, searching, and managing files efficiently. Traditional Java file I/O often looks like this: try (BufferedReader br = new BufferedReader(new FileReader(file))) { String line; while ((line = br.readLine()) != null) { if (line.contains("config=")) { // Logic buried in 20+ lines } } } catch (IOException e) { // More boilerplate } Search/Replace requires manual loops and backup…  ( 7 min )

If you’ve ever tried to move from one major version to another, you know it’s not just about running bundle update rails and calling it a day.

🦄 Any time I make a plan—like last week’s noble intention to finish part two of my slightly theoretical, totally manual AI attribution solution—the universe just laughs. I’ll finish that one soon, I swear. But October’s almost over somehow, and I’m just as confused about that as you are! 🎃 Anyway—this unscheduled detour has a good reason. 🌊 The flood of questions about Copilot’s premium request limits is back, right on schedule. If you added up the messages from every random channel I watch, you could set an atomic clock by this monthly “why am I out of requests?” panic. The closer we get to the first of the month, the faster the confusion multiplies. These limits are constantly misunderstood, misquoted, or just plain outdated. Honestly, that’s not really surprising—GitHub changes billi…  ( 15 min )

C# 14 is almost here, so it's time for our annual feature overview. This year brought fewer changes than the last. Some might consider them minor, but is it really so? Let's take a closer look. Yes, we can now omit writing a field for a property. Some might say that we could already write properties like this: public string Name { get; set; } This is an auto-implemented property, which creates a hidden field. However, the problem is that it can only be used when no additional logic is required. If we need such logic, we have to create a field just to store the data so we could process it in the property setter. For example, when we need to trim whitespaces from an email address before saving it, we would typically write something like this: public class User { private string _oldEmail;…  ( 12 min )

GitHub Home It was another Black Friday. At 3 AM, my phone started screaming like crazy. 😱 It wasn't my alarm; it was the monitoring alert. Our flagship e-commerce service, the system we had poured six months of hard work into, had crumbled like a paper house in the face of peak traffic. CPU at 100%, memory overflows, and logs filled with timeout errors. 💸 That night, we lost millions in sales and, more importantly, our users' trust. It was one of the darkest nights of my career. 🔥 From that day on, I understood a principle: performance is not an option; it is the lifeline of a service. As an old-timer who has been in the coding world for nearly forty years, I've seen too many teams make mistakes when it comes to performance. They are either too optimistic, believing that "hardware will…  ( 10 min )

Hey #Symfony developers and #webdev community! Are you constantly battling those frustrating Access-Control-Allow-Origin CORS errors, especially when dealing with OPTIONS preflight requests from your frontend? You're not alone! The common pitfall is that OPTIONS requests often arrive without any payload or route parameters, causing Symfony's router (and especially #[MapRequestPayload]) to fail before CORS headers can be applied. Instead of reaching for a heavy bundle, here's a professional, lightweight solution: an Event Listener. By implementing a CorsSubscriber on the KernelEvents::REQUEST event with a high priority (e.g., 9999), you can intercept all OPTIONS requests right at the start of the Symfony lifecycle. This listener can then construct an immediate HTTP 200 response, inject the necessary Access-Control-Allow-* headers, and prevent further processing (like routing or DTO mapping). This approach ensures your API sends the correct CORS signals to the browser, unblocking your frontend operations. It's a clean, performant, and framework-native way to achieve full CORS compliance. For a full code example, detailed explanation, and best practices, check out the complete guide on my site: https://agconsulting.altervista.org/symfony-cors-risolvere-errore-options/  ( 6 min )

A while ago in a technical interview I got asked: “Can you walk me through how authentication and authorization actually work under the hood?” And like many devs I knew just enough to plug in Auth0/NextAuth etc… but not enough to explain the “why” behind the flow. This series is the version I wish I had back then — plain English, no magic ✨, just a mental model that sticks. Because the frontend knows nothing about you. To your browser, you’re just: a tab with JavaScript, a user… or a hacker, or possibly a fridge 🧊 with Chrome 😅 It needs someone trusted to say “yes, that’s really Sylwia.” → that “someone” is the IdP.

Ever clicked through your web app on multiple browsers and noticed something looked slightly off—or worse, a feature didn’t work at all? That’s why cross-browser testing is essential. Users expect your app to work seamlessly on Chrome, Firefox, Safari, Edge, and even some legacy browsers. Any hiccup can affect user experience, trust, and ultimately your business. The good news? Open source testing tools make this process a lot easier. By automating browser tests, you can quickly spot inconsistencies and ensure your app behaves the way it should—without spending hours manually checking each browser. Why Cross-Browser Testing Makes a Difference? Modern web apps are complex, and different browsers interpret HTML, CSS, and JavaScript in slightly different ways. Some common challenges include…  ( 8 min )

Most people in IT have at least heard of assembly language. Some even saw it during university - just enough to know it exists, but not enough to use it for anything real. Assembly used to be the secret behind high-performance code. Games like Quake, graphics engines, and device drivers often had big chunks written in assembly for one simple reason: speed. But times changed. Modern developers rarely touch assembly anymore, and for good reasons. Until recently, it simply didn't make sense for most projects. Well, at least, that's what I thought - until I tried something on my Mac a few days ago. Assembly slowly vanished from mainstream software development because it was too much work for humans to handle. It's not portable - an assembly routine that runs on x86 won't work on ARM, RISC-V, o…  ( 9 min )

One of the key challenges in a food delivery service is ensuring that orders reach customers quickly while minimizing courier idle time (the time when they're online but without an active order). It seems simple: a customer places an order, the restaurant prepares it, and all that's left is to find the nearest available courier and send them to pick up the food. However, in reality, it's much more complex. In this article, I'll explain how we select the optimal courier for each order and how our approach has evolved over time. I'll cover two fundamentally different methods for solving this problem.

Introduction When I am handling processes that can be a heavy load on my server, I like to create a sort of queuing system to handle each process one by one, so that if there is a chance of the server being overwhelmed, this can help prevent it. This kind of system can be used on both the client side and the server side. Today's blog, I am going to do a quick guide on how I set up a basic queue system for an application, one that focuses on dealing with them one by one and another that batches them in groups. To get started on the queue system, you can use functions or a class. But for today, I am going to use a class to demonstrate, but to make a function version, you are just splitting up the work into smaller bite-sized code. So first, we are going to create a class called QueueSyst…  ( 9 min )

Java Try-With-Resources: Your Ultimate Guide to Clean & Leak-Proof Code Let's be real for a second. How many times have you written a Java program that reads a file, connects to a database, or does anything that involves opening a connection to something? And how many times did you have to wrap that code in a try-catch-finally block that was longer than the actual logic? You know the drill. You open a FileInputStream in the try, do your work, and then in the finally block, you have to check if the stream is not null and then call .close() inside another try-catch because, well, .close() can also throw an exception! It's a mess. It's boilerplate. It's the kind of code that makes you sigh before you even start typing. It felt like this: java // The old, painful way FileInputStream fis = n…  ( 10 min )

Managing database backups manually can be error-prone and time-consuming - especially across environments. With Laravel's Artisan commands, you can automate MySQL backups and restores within your application. In this post, we will implement two commands: php artisan database:backup - creates a SQL backup of your database. php artisan database:import your_backup_file.sql - restores a database from that backup. Both use Symfony's Process component to call MySQL tools (mysqldump and mysql) directly from PHP.

In August 2020, nearly 40% of A-level students in England saw their grades downgraded by an automated system that prioritised historical school performance over individual achievement. The algorithm, designed to standardise results during the COVID-19 pandemic, systematically penalised students from disadvantaged backgrounds whilst protecting those from elite institutions. Within days, university places evaporated and futures crumbled—all because of code that treated fairness as a statistical afterthought rather than a fundamental design principle. This wasn't an edge case or an unforeseeable glitch. It was the predictable outcome of building first and considering consequences later—a pattern that has defined artificial intelligence development since its inception.

Transit Gateway (TGW) is a service that connects multiple VPCs and on premises networks using a single gateway. Before Transit Gateways if you had multiple VPCs that needed to talk to each other, you had to create multiple peering connections. Each connection required manual routing, was non-transitive and hard to scale. TGW solves this by acting as a regional layer 3 router which provides transitive connectivity between attached VPCs, centralised control over routing and propagation, and can scale to thousands of VPCs. TGW Attachments are the connections between the TGW and the VPCs or VPNs. Each attachment represents a link between a specific VPC or VPN and the Transit Gateway, allowing for efficient traffic routing. Without attachments the TGW doesn’t even know those VPCs exist. A TGW by default has one route table and all other attachments use this for table for routing decisions. Routes are propagated from the attachments. A route table can contain static routes, propagated routes automatically learned from attachments that you enabled to propagate into this table and blackhole route with “blackhole = true” to drop matching traffic and prevent specific paths. TGW makes a routing decision based on the route table associated with the ingress attachment. This means that traffic entering from Attachment A will look at A’s associated route table to decide where to send the packet next. Return traffic will look at the returner’s associated table to avoid asymmetric routing. An association binds one TGW route table to an attachment and determines which route table a connection (attachment) uses. That table governs egress from that attachment and you can re-associate an attachment to a different TGW route table at any time. Propagation lets an attachment advertise its network prefixes into a TGW route table automatically so other attachments associated with that table can reach it without manual static routes. You turn propagation on per attachment per TGW route table.  ( 7 min )

Let's explore ten exceptional API clients that maintain full functionality even when your internet connection fails you. When it comes to compre…  ( 9 min )

🚀 A Glimpse Into the Future of Browsing You know that feeling when technology just works — like pure magic? So, I thought, what if I asked AI to do everything for me? Talking to My Browser I opened Comet and typed this into Perplexity: “Open YouTube, find the official NASA Moon landing video and jump to the moment Armstrong says ‘one small step for man.’” All that — without me touching the keyboard again. 🤯 🌐 Why This Is So Impressive This moment really hit me. 🧩 What Makes Comet + Perplexity Special Here’s why this little experiment blew my mind: Contextual Understanding Perplexity understood what I meant, not just what I said. It identified the “official NASA Moon landing video” and ignored unrelated clips. ⚙️ Try It Yourself If you want to see how it feels to command your browser with just words: Download Comet Browser Open a new Perplexity tab and ask: “Open YouTube, find the official NASA Moon landing video, and jump to Armstrong’s first step.” Sit back and watch as it does everything automatically. You’ll understand instantly why people are calling Comet the future of human–AI interaction.  ( 9 min )

The last time I felt like a programmer, people who wrote programs called themselves that (not Devs). So, hi. A long time ago, I didn't finish my computer science training. I wanted to make software when I grew up ... but, I never did. For clarity, this was a long while ago. Some time shortly after the Millennium bug didn't end the world, but before the first internet bubble had properly burst. It was around a time when the mini-disk was the best piece of technology known to man (and, fwiw, imo, it perhaps still is). Before burning out of college in a mad few months of mostly partying, I had been on cruise control. I was well on my way to starting a career in the one thing I ever thought I was good at.

Let's be honest: playing with large language models is amazing, but seeing that OpenAI API bill at the end of the month can be... painful. 😅 I've been working with the GPT-4 and GPT-3.5 APIs a lot, and I noticed how quickly the costs can spiral out of control. A simple task routed to GPT-4 by mistake, an inefficient prompt, or running the same query over and over—it all adds up. I kept thinking there had to be a smarter, more automated way to manage this without rewriting all my code. That's why I built CostLens, a simple SDK I'm hoping can help other developers who are facing the same problem. At its core, CostLens is a drop-in SDK that automatically helps you cut your AI costs.

In today’s fast-paced software world, logging often gets treated as an afterthought—a few lines sprinkled here and there before a release. But when a production incident strikes at 3 AM, those logs become your North Star ✨ for making sense of chaos. After years in backend engineering and incident response, it’s clear: logging isn’t just about recording events—it’s about building observability into your system from day one. 💡 Research shows developers spend up to 35–50% of their time debugging issues. And a big chunk of that time is wasted digging through incomplete logs or trying to guess what really happened.

Managing large Excel files can often be a daunting task, especially when different sections of the data need to be distributed, analyzed separately, or simply made more manageable. Imagine a scenario where a single Excel workbook contains sales data for multiple regions, and each region's data needs to be sent to its respective manager. Manually copying and pasting data into new files is not only time-consuming but also prone to errors. This article addresses this common pain point by providing a practical C# solution to efficiently split Excel worksheet data into separate files programmatically, leveraging a powerful third-party library to simplify the process. The necessity to split Excel files arises in various professional contexts. For instance, in financial reporting, specific depart…  ( 8 min )

This approach allows you to extract data accurately and automatically—freeing you from repetitive manual work. Python’s unmatched advanta…  ( 8 min )

Introduction In today’s world, almost every app you use — from Netflix to Spotify — runs on AWS (Amazon Web Services). But how does AWS actually work behind the scenes? The AWS Flow Explained The AWS architecture is built on a client-server-cloud model. Client This is where everything starts. The client can be: A web browser, A mobile app, or Any IoT device sending a request. The client sends a request (like logging in, fetching data, or uploading a file) to AWS servers. AWS Cloud Layer This is the core of the process. EC2 for computation (running servers and apps), S3 for storage, RDS for database management, Lambda for serverless execution. The AWS Cloud acts as the brain — managing scalability, security, and speed automatically. Database & Application Layer Here, the actual data and logic live: Database: Stores your user information, transactions, etc. Application Layer: Runs your backend code, APIs, or microservices. Both layers work together to process your request efficiently and securely. Network Layer Once AWS has processed everything, the results are sent back through its high-speed global network. User Finally, the user sees the response — maybe a webpage, dashboard, or streaming content — all delivered instantly thanks to the AWS global infrastructure. Why AWS Flow Matters Understanding this flow helps you design scalable and fault-tolerant systems. You can optimize how your app connects to the cloud. You learn to separate computation, storage, and networking for performance. You get a clearer idea of where services like CloudFront, Route53, or IAM fit in. Developer Takeaway AWS isn’t just hosting — it’s an entire ecosystem that powers millions of apps. AWS makes cloud computing simple — but understanding how its flow works internally gives you a professional edge. Whether you’re building a small portfolio project or an enterprise-grade app, knowing this structure helps you think like a cloud architect.  ( 7 min )

The Unintended Consequences of Superintelligence As the world grapples with the rapid advancements in artificial intelligence (AI), a growing concern has emerged among some of the most prominent figures in the field. Recently, Prince Harry and his wife Meghan have joined forces with AI pioneers to call for a ban on superintelligent systems. What is Superintelligence? Before we dive into the implications, let's define what superintelligence refers to. In simple terms, it's an AI system that surpasses human intelligence in all domains, potentially leading to unforeseen consequences. Some experts argue that developing such systems could pose a significant threat to humanity, much like nuclear power did during the Cold War era. The Concerns Surrounding Superintelligence There are several reaso…  ( 7 min )

Artificial Intelligence (AI) is evolving beyond single, monolithic models. Today’s most capable systems are made up of multiple AI agents. This new paradigm of multi-agent systems (MAS) represents the next step in AI evolution, where collaboration and coordination between agents matter as much as individual intelligence. In this article, we’ll break down what multi-agent systems are, how they work through real-world analogies, and explore the different architectures that make them scalable and effective in practice. With the rapid development of Large Language Models (LLMs), many systems are now built around an LLM core (ChatGPT, Claude, LLaMA, etc.) and extended with prompts, functions, or pipelines to perform specific tasks. These systems are known as LLM Agents. There are several types …  ( 12 min )

こんにちは！今日は、APIドキュメントにまつわる絶望的な状況からどうやって抜け出したのか、実際の体験を赤裸々にお伝えします。 「このAPIドキュメント、最新じゃないよね？」 先週、フロントエンドエンジニアとの連携で痛い目を見ました。決済APIの結合テストで、彼が私が3日前に共有したドキュメント通りにパラメータを渡しているのに、ずっと「パラメータ形式エラー」が返されるという事態。結局、コードを確認して、注文金額フィールドの型をintからfloatに変更したのに、ドキュメントの更新を忘れていたことに気づきました。 フロントエンドの同僚に「ドキュメント見るより直接コード見た方が早いよ」と笑われたときは、さすがに心が折れそうになりました… これまで私たちのAPIドキュメントはMarkdownでの手書きが主流でした。これによる苦労話は尽きません： 更新地獄：インターフェースパラメータが変わるたび、手動でフィールド説明、リクエスト例、レスポンスサンプルを同期する必要があり、イテレーションが速いとまったく追いつかない テストの難しさ：登録APIに電話番号形式の検証を追加したとき、ドキュメントに記載し忘れたため、テスト担当者が11桁の電話番号でエラーが出る理由を半日も理解できず バージョン混乱：共有リンクを更新するたびに再配布が必要で、誰かが古いバージョンを持っているとコミュニケーションコストが爆上がり まさに「労多くして功少なし」の典型で、チーム全体の協業効率が大きく低下していました。 状況が一変したのは、EchoAPIでインターフェース管理を始めてからです。 AI一键補完インターフェースドキュメント 私が最初に惹かれたのは、「デバッグ即ドキュメント」という考え方： インターフェースをデバッグした後、「ドキュメント補完」をクリックするだけで、フィールドタイプ、必須項目、レスポンスサンプ…  ( 5 min )

You know, I was chatting with a friend the other day — she’s a travel agent who’s been in the business for over 15 years — and she said something that stuck with me. “People just don’t call anymore,” she laughed. “They message on WhatsApp, scroll through Instagram, and expect to find everything online.” And honestly? She’s right. The way people plan trips has completely changed. Travelers today — whether it’s a honeymoon couple or a digital nomad — aren’t waiting around for brochures or long phone calls. They’re Googling. They’re comparing. They’re clicking. That’s why, if you’re a travel agent in 2025 and you still don’t have your own website, you’re missing out on the easiest way to attract modern travelers. Big time.

Microservices with Node.js: A Comprehensive Guide Introduction In the dynamic landscape of modern software development, the monolithic application architecture is increasingly making way for more flexible and scalable approaches. Among these, the microservices architecture has emerged as a leading solution, particularly favored for complex and evolving applications. Microservices involve breaking down a large application into a collection of small, independent, and loosely coupled services that communicate over a network. This architectural style promotes agility, resilience, and independent deployability. When paired with Node.js, a lightweight and powerful runtime environment built on Chrome's V8 JavaScript engine, developers gain a potent combination for building efficient and scalab…  ( 10 min )

App Store: link Most productivity tools push output. They want more tasks, more deadlines, more alerts. Clarity does not come from doing more. It comes from knowing what deserves attention. I like the Getting Things Done (a book about getting things done) idea of capturing everything so the mind can relax. I wanted a quieter way to do that. Mind Backlog is my take on GTD: capture, clarify, choose, and move on with less noise and more care. Think of your thoughts like a lightweight sprint board. Ideas, questions, and unsolved problems live here. Backlog is not failure. It is permission to let something rest until you are ready. Items you are tackling in this sprint. You decided they are solvable now or worth your energy today. Resolved or released. The goal is not endless checkboxes. The goal is to release mental load. You write what is on your mind. The app asks one question: Can I solve this right now? If yes, send it to What's the next Task. If not, let it rest in Backlog. Can I name the next action? If yes, send it to Active. If not, we will keep it warm in the Backlog. No due dates. No streaks. No pressure. Just a simple flow that helps you think clearly and act with intention. This is not a task grinder. It is a thought organizer. It helps you notice what is calling for attention, sort what is actionable, and let the rest breathe until you are ready. Sometimes the best productivity tool is not the one that makes you do more. It is the one that helps you think better.  ( 6 min )

I’ve lost count of how many times I’ve spun up a new Express app just to test something. Then I forget the command I used, Google it, and end up watching yet another “Build a REST API in 30 Minutes” video on YouTube. Sound familiar? Express.js is the backbone of so many backend projects — from side hustles to serious production systems — but actually learning it well takes more than copy-pasting from tutorials. So, after testing a bunch of learning platforms, here’s my honest breakdown of what’s worth your time in 2025. Let’s be real: you can technically ship an API with just a couple of lines of Express.

The Rose’s Whisper: ADC as the Listener 🥀 On his tiny planet, the Little Prince kneels by his rose, her petals trembling. “What’s wrong?” he asks, but her voice is a soft sigh—a voltage too faint for his notebook (microcontroller) to read. Then he finds a golden ear (ADC) tucked in the grass, etched with “Translate.” “Hold still,” he says, pressing the ear to her stem. The ear hums, sorting her whispers into numbers: 36.2°C—Thirsty, but brave ✨. “How?” the prince asks. The ear chuckles: “I’m a SAR ADC—like you guessing her favorite water amount: ‘Is it 10ml?’ ‘No, 5ml?’ Until I find the truth.” Nearby, a Sigma-Delta ADC (a fox-eared device) sits, patient: “I listen longer,” it says, “like the fox waiting to be tamed—hearing every quiver, even the quiet ones.” The rose smiles: “Finally, so…  ( 8 min )

Every team has that one person, or two, who insists that “frontend tests are a waste of time.” They might say E2E tests are flaky, or that QA already does the job. But deep down, skipping tests isn’t a bold time-saving move; it’s a long-term productivity trap. Here’s how to win the argument (and save your project from endless regressions). Frontend changes are deceptively simple. You tweak a component or update an API call, and suddenly the login form stops working. Having automated tests for critical flows (login, checkout...) ensures that your app’s core functionality never silently breaks. Without tests, the real testers are your users, and they’re the worst kind of testers. Fixing a bug found in production takes exponentially more time than catching it during development. Manual QA can…  ( 7 min )

While other databases out there might shard, CouchDB is one of the few that does it automatically and saves you the annoying — read error-prone — work of setting it up yourself. Being unique in this way, it’s a topic you may not know too well. The arcane-sounding term (especially if it reminds you of the prismatic variety) doesn’t need to conjure confusion or intimidation. In this post, we’re going to take a deeper look at scaling CouchDB with shards: what sharding is, plus why and how to do it. Any given central processing unit (CPU) — the thing on which your database lives — has a physical limit to how much processing it can do at one time. By extension, there’s a limit to how big your database can get if you still want to do useful things with it if it can only run on a single core. D…  ( 15 min )

Lexical Scoping means: "Variables are accessible based on where they are written in the code — not where they are called." Imagine your house has rooms. If you leave your phone in the living room, you can use it there. But if you go to the kitchen, you can’t use your phone unless you bring it with you.

Stage 1 of the HNGi13 QA Track focused on reviewing requirement documents and translating them into an actionable test plan. For this task, I worked on Gradific, a grading and task management platform for educators. My goal was to understand how features like workspace creation, assignment setup, and grading flow together, and then design a testing strategy around them. I started by analyzing the PRD and FRD, identifying core functionalities and edge cases. From there, I created a structured Test Plan outlining objectives, scope, approach, risks, and deliverables. I also designed 10 detailed test cases to validate and verify that the requirements are met and the system works as expected.

In today’s fast-paced business world, organizations are constantly juggling countless communications, projects, and data streams. From Slack messages to emails, meetings, and shared documents, the sheer volume of information can overwhelm even the most organized teams. Yet, the most successful organizations operate like a finely tuned organism. Their secret? A “nervous system” that connects people, information, and workflows seamlessly. In this blog, we explore how building the nervous system of your organization can transform productivity, collaboration, and decision-making. Without a nervous system: Knowledge gets siloed in private chats or individual heads Every conversation, file, and decision is captured and connected Too many tools fragment information. Teams switch between Slack, email, Trello, and Google Drive, losing time and focus. Centralizing communication into one intelligent workspace ensures that: Conversations are linked to tasks, decisions, and files Automatically extract action items from meetings and messages Step 3: Connect Teams to Expertise Match questions or problems to team members with relevant skills Step 4: Make Data Actionable Convert conversations into searchable knowledge Step 5: Foster a Culture of Transparent Communication Encourage teams to share context instead of hiding it in DMs Why Nexy is the Nervous System Your Organization Needs Capture and store every conversation, file, and decision Conclusion Address — Company Name — Nexy Location — Netherlands  ( 8 min )

Abstract We introduce the Beta-Rho Orthogonality (BRO) score, a novel metric that quantifies the consistency between systematic risk exposure (beta) and correlation in cryptocurrency markets. Unlike traditional metrics that treat beta and correlation as separate measures, the BRO score reveals structural market relationships by examining their ratio. We demonstrate that this simple formulation serves as a multi-purpose analytical tool for: (1) detecting regime stationarity, (2) identifying tradeable structural relationships, (3) classifying predictability, and (4) constructing market-neutral portfolios. Our framework reveals four distinct behavioral regimes in crypto markets and provides a quantitative basis for distinguishing between manageable volatility and unmanageable chaos.

Microsoft’s decision to end support for Windows 10 isn’t just another software update—it’s a declaration: Your device is no longer yours to control. Millions of machines, still powerful and capable, are now deemed obsolete, not because they’ve broken down, but because a corporation decided their time was up. This isn’t just an ecological scandal; it’s a reminder that when you buy a computer, you’re not truly buying freedom. You’re entering a lease agreement, where the terms can change—or terminate—without your consent. What if you could use your hardware for as long as it lasts, without arbitrary restrictions or forced upgrades? That alternative exists, and it’s called Linux.

I’m excited to announce that three of my UI designs were showcased during the Appian Community’s UX Design Lab | Mobile & Responsive Design livestream! 🎉 Seeing my work highlighted alongside so many creative and thoughtful submissions was an amazing experience. The session, hosted by Christine Danzi and Jennifer Higa, focused on the principles that make Appian applications not just functional — but intuitive, responsive, and user-friendly across all devices. Building for responsiveness goes beyond scaling layouts. Here are some of the core insights shared during the session that every Appian designer should keep in mind: Ensure that essential information remains visible and accessible on smaller screens without overwhelming the user. Design navigation structures that feel natural for mobile interactions — like bottom tabs or collapsible menus. Buttons, links, and interactive components should have ample spacing for easy tapping and accessibility. Use Appian’s dynamic layouts and conditional visibility to modify component behavior based on device size. Always test your designs on different screen widths to ensure consistent experiences across mobile, tablet, and desktop. Here’s a quick look at the responsive UI submissions that were featured in the livestream: A huge thanks to Christine Danzi and Jennifer Higa for hosting such an engaging session and providing valuable feedback on making Appian designs truly responsive. Events like these highlight the power of community learning — where every designer, developer, and contributor helps push the boundaries of what’s possible in low-code UX design.  ( 8 min )

Protect your web applications from automated content theft and AI data harvesting. In recent years, the rise of artificial intelligence has accelerated data collection across the internet. Many AI models rely on large-scale web scraping to feed their algorithms. Unfortunately, this often means that your website content — articles, APIs, or even private datasets — may be harvested without consent. These AI scrapers operate differently from ordinary bots. They mimic real browsers, rotate IPs from various countries, and simulate human-like behaviors to bypass traditional security tools. Some even execute JavaScript or use headless browsers such as Puppeteer or Playwright to collect dynamic content.

Optimistic Superposition: A Quantum Leap for AI? The dream of truly intelligent AI hinges on our ability to train complex models, a process currently bottlenecked by sheer computational cost. Imagine training a model not in weeks or months, but in hours. What if we could explore solution spaces previously deemed intractable? This is where "optimistic superposition" comes in. At its core, it's a novel algorithmic approach designed to handle complex problem-solving by strategically delaying computationally intensive calculations. Instead of immediately tackling every possible scenario, the algorithm makes optimistic assumptions, carries these assumptions as constraints, and only resolves them when absolutely necessary. This "wait-and-see" approach drastically reduces the initial computati…  ( 7 min )

GitHub Home I remember a few years ago, I was leading a team to develop a real-time stock ticker dashboard. 📈 Initially, everyone's enthusiasm was incredibly high. We were all excited to build a "live" application with our own hands. But soon, we found ourselves stuck in the mud. The tech stack we chose performed reasonably well for ordinary REST APIs, but as soon as WebSockets came into the picture, everything became unrecognizable. Our codebase split into two worlds: the "main application" that handled HTTP requests, and a "separate module" that handled WebSocket connections. Sharing state between these two worlds, like a user's login information, became a nightmare. We had to resort to some very clever (or rather, ugly) methods, like using Redis or a message queue to synchronize data. …  ( 10 min )

This post is my submission for DEV Education Track: Build Apps with Google AI Studio. I built an intelligent calorie tracking application that leverages the Gemini API to provide users with personalized, healthy meal suggestions. The app helps users monitor their daily food intake and receive AI-powered recommendations to better achieve their dietary goals. My key prompts used: https://calorie-companion-seven.vercel.app What surprised me most was the speed at which I could build a genuinely useful AI feature. Simple and powerful it is to integrate the Gemini API to create dynamic, context-aware user experiences. With just a single API call, the application can provide high-quality, relevant nutritional advice that adapts to the user's real-time input, turning a basic calorie counter into a personalized dietary companion.  ( 6 min )

Tired of typing passwords every time you log into a server via SSH? Passwordless SSH authentication using SSH keys is the way to go. It’s secure, efficient, and saves you time. In this guide, I’ll walk you through setting it up in just 5 minutes. Let’s dive in! Prerequisites Two machines: One to act as the client (your local machine) and another as the server (remote machine). SSH installed on both devices (most Linux/macOS systems have it pre-installed). Basic Linux/macOS command-line knowledge. Step 1: Generate an SSH Key Pair on Your Client Open your terminal and run: ssh-keygen -t rsa -b 4096 Press Enter to accept the default file location (~/.ssh/id_rsa). You can skip setting a passphrase for simplicity, but it’s recommended for added security. This creates two files: ~/.ssh/id_…  ( 7 min )

Introduction At Lingo.dev, I write a lot of TypeScript code. I'm definitely not a wizard, but I do try to play with features that go beyond the basic types. This post describes a number of features (and when you might want to use them) to help you expand your knowledge beyond the absolute fundamentals. as const assertions By default, arrays and objects are mutable, and TypeScript widens literal values to their general types. This makes it harder for TypeScript to help you catch bugs and provide accurate autocomplete. const colors = ["red", "green", "blue"]; // Type: string[] - could be any strings colors.push("yellow"); // Allowed, might not be what you want type Color = (typeof colors)[number]; // string (too general!) Use as const to make everything readonly and preserve literal ty…  ( 17 min )

Beyond Binary RAG: Enhancing Decision-Making with Nuanced Risk Assessment The all-too-familiar Red, Amber, Green (RAG) system has become a staple in risk management and decision-making processes across various industries. However, an over-reliance on this binary approach can lead to oversimplification of complex issues, resulting in inadequate risk assessment and suboptimal decision-making. The Problem with Binary RAG The traditional RAG system categorizes risks into three distinct states: Red: High-risk or critical situations that require immediate attention. Green: Low-risk or stable situations that require minimal attention. Amber: Medium-risk or uncertain situations that require monitoring. While this system provides a basic framework for risk assessment, it often fails to capture the nuances of complex issues. The binary nature of RAG can lead to: False negatives: Critical risks being overlooked due to their classification as Amber. **... This post was originally shared as an AI/ML insight.

The debate surrounding AI-powered ad personalization has sparked concerns about the potential loss of cultural diversity and creativity in advertising. On one hand, AI algorithms can analyze vast amounts of data to create highly targeted and effective ad campaigns that resonate with specific audience segments. However, this may lead to a homogenized consumer experience, where people are shown the same ads repeatedly, reinforcing existing biases and limiting exposure to diverse perspectives. To mitigate this risk, AI-powered ad personalization can be designed to foster cultural diversity and creativity in advertising. Here are a few strategies: Diverse data sources: Implement data collection methods that actively seek out diverse perspectives, such as partnering with community organizations, social media groups, or cultural influencers. This ensures that the AI algorithm is exposed to a wide range of experiences and viewpoints. Inclusive modeling: Use AI models that p... This post was originally shared as an AI/ML insight.

Many challenges in AI products stem less from choosing frameworks and more from how user experience (UX) and architecture shape each other. I first noticed this while using ChatGPT to draft and maintain product requirement documents (PRDs) — reusing prompt variants, manually curating context, and constantly tweaking outputs to stay aligned. The workflow technically worked, but it felt brittle and overly manual. That experience raised a question: What might it take for an agentic workflow — a coordinated system of specialized LLM sub-agents orchestrated by code rather than a single prompt — to produce and maintain a complex artifact like a PRD without so much manual prompting, context oversight, and guesswork? More broadly, how could changes in architecture and UX design improve usability,…  ( 13 min )

🧠 Introduction: A New Way to Code Is Emerging For decades, coding has meant writing lines of code manually—debugging, optimizing, and maintaining them over time. But in 2025, a new wave of development is rapidly transforming that model: Vibe Coding. Vibe Coding is an AI-first programming paradigm where developers describe what they want, and intelligent agents handle much of the code generation. Instead of spending hours crafting functions line by line, engineers focus on high-level logic, problem framing, and iterative refinement. This isn’t just another “no-code” trend—it’s a fundamental shift in how we build software. At its core, Vibe Coding means: Developers express intent in natural language or structured prompts. AI agents generate, refactor, and optimize code automatically. The …  ( 8 min )

"China's robotics has the advantage of having integrated AI into much lo…

Presented by Arm A simpler software stack is the key to portable, scalable AI across cloud and edge. AI is now powering real-world applications, yet fragmented software stacks are holding it back. Developers routinely rebuild the same models for different hardware targets, losing time to glue code instead of shipping features. The good news is that a shift is underway. Unified toolchains and optimized libraries are making it possible to deploy models across platforms without compromising performance. Yet one critical hurdle remains: software complexity. Disparate tools, hardware-specific optimizations, and layered tech stacks continue to bottleneck progress. To unlock the next wave of AI innovation, the industry must pivot decisively away from siloed development and toward streamlined, e…

And I... wasn't. After eight hours of solving problems, writing code, and staring at a screen, the last thing I wanted to do was more of the same. I'd force myself sometimes, opening my laptop with a sense of dread, only to produce low-quality code and feel even worse. I thought this meant I wasn't "passionate" enough.

In this project, we explored model evaluation metrics using a Lead Scoring dataset. The goal was to identify which factors most influence lead conversion and evaluate how well our model can predict them. Below are the key concepts and lessons learned throughout the assignment. A lead scoring model helps businesses identify which leads (potential customers) are most likely to convert. By assigning a score to each lead, sales teams can focus their efforts where it matters most — improving conversion rates and efficiency. In our dataset, the target variable (converted) indicates whether a lead converted (1) or not (0). The features included data such as: lead_score number_of_courses_viewed interaction_count annual_income Before modeling, we performed crucial preprocessing steps: Handling Miss…  ( 7 min )

Every great application begins with a simple, honest object. It does its job, it tells the truth, and it asks for little in return. It’s the UserService that fetches data, the Image that renders itself, the API that returns a response. But as our systems grow from humble scripts to sprawling architectures, this honesty becomes a liability. A naïve UserService can buckle under a million requests. A direct Image load can freeze a UI. A raw API call can be a gaping security hole. We need a guardian. A diplomat. An illusionist. We need the Proxy Pattern. This isn't just another Gang of Four entry.

Author: Samantha Laine King Last Updated: October 2025 This guide walks through adding a clean, accessible Dark Mode toggle to a React application using Tailwind CSS and localStorage. It covers setup, theme persistence, and best practices for accessibility. Tailwind provides built-in dark mode support. In your tailwind.config.js file, enable class mode so users can manually toggle it: // tailwind.config.js export default { darkMode: 'class', theme: { extend: {}, }, plugins: [], } This allows you to switch themes by adding or removing the dark class on the root element. We’ll use a custom React hook to manage theme state and persist it in localStorage. // useDarkMode.ts import { useEffect, useState } from 'react' export default function useDarkMode() { const [theme, set…  ( 7 min )

Automata Alchemists: Transmuting Reinforcement Learning into State Machines Tired of hand-coding complex state machines? Imagine a world where your machine learning model automatically infers and implements them! What if we could leverage AI to build AI? The future of program synthesis might be closer than you think. Think of a reinforcement learning agent exploring an environment, learning optimal actions to maximize a reward. We can repurpose that learned behavior to define the state transitions of an automaton. Instead of rewarding specific actions, we reward reaching desired states or completing specific sequences of actions. The result is an automated process to build Finite State Machines that execute deterministic sequences. We essentially train an AI to become a DFA. The agent ex…  ( 7 min )

Hey everyone, If you're a developer, you've probably been in this situation: a client sends you a database_dump.sql file, or you need to set up a local copy of a production database for testing. The usual process is tedious: Install the correct database server (Postgres? MySQL?) Create a new user and database Figure out the right command-line flags to import the .sql file Hope there are no version conflicts It's a frustrating 15-minute detour from the work you actually want to do. I got tired of this workflow, so I built a solution right into my app, FormPipeDB. It's a feature that allows you to take an entire SQL script—CREATE TABLE statements, INSERT INTO statements, and all—and turn it into a live, fully manageable database just by pasting it into a textbox. Here's how it works: Click "Import SQL..." Paste your entire SQL script. Click "Import Database." That's it. The app parses the script, creates all the tables, defines schemas, populates the data, and even builds foreign key relationships for you. You go from a static .sql file to a fully interactive database you can edit and query visually in less than a minute. This has been a game-changer for my workflow, especially for: Faster Prototyping: Instantly spin up a backend from an existing schema. Easy Debugging: Quickly load a snapshot of production data to test against. Client Work: Set up a database for a client project without any server configuration. The app is called FormPipeDB. I'm on a mission to get my first 100 paid users, so I'm running a $99 lifetime deal. I'd love for the dev.to community to check it out and give me honest feedback. You can try it at formpipedb.com.

Starting Out — and Feeling Lost I started my full stack software engineering career right out of college as a bright-eyed, bushy-tailed computer science graduate with terrible impostor syndrome. Who can relate? Between the firehose of onboarding information, a brand-new work environment, and an unfamiliar schedule, I felt completely overwhelmed. IBM ran large cohort-based onboarding workshops, and on top of that, I was meeting with different members of the team to learn as much as possible before jumping into real work. When the time came to tackle my first ticket, I was clueless.

The Realization I was working with Claude on some gnarly legacy code when it hit me: I’ve been vibe coding long before anyone called it that. You probably know what vibe coding is, even if you’ve never heard the term. It’s often pinned on junior devs who use AI to write code they barely understand—but real vibe coding is something else entirely. It’s what experienced developers do when we glance at a block of code and just know if it’ll work. We skim Stack Overflow, yank in half-understood libraries, and adapt stranger-solutions to weirdly specific problems. To new devs, it looks like wizardry. To us, it’s Tuesday. And here's the kicker: everyone treats AI-assisted coding like uncharted territory, as if we're all stumbling into the future hand-in-hand. But we’ve been collaborating with “…  ( 11 min )

Directional Light: With this in mind theres no reason to calculate how each fragment compares the the light source position, since they are all coming from the same place essentially. So lets remove that from our light struct and change the lightDir calculations accordingly. And this should be the result. (Dont forget to set a direction for the light struct either!) Point Light: Faking fading light looks kind of fake without the proper mathematical equation, point lights tend to shine bright at a close position but quickly fall of as you get slightly further away, less of a gradual fade and more of…  ( 8 min )

When AWS experienced a global outage, it disrupted more than cloud services — it disrupted learning. As an ALX AWS Cloud Architect observer, I watched how the outage impacted Vocareum labs and brought cloud resilience principles to life. Here’s what it taught us about designing for failure, recovery, and real-world reliability. On October 20th, 2025, something strange happened — AWS went dark. At first, it felt like a typical hiccup. But soon, messages started pouring in across the ALX Cloud Architect community: “My Vocareum lab won’t load.” It wasn’t just one of us. It was everyone. The Ripple Effect The outage didn’t just stall projects — it became a live case study. Students running hands-on labs couldn’t deploy instances, monitor workloads, or test automation pipelines. For many, it was frustrating. For others, it was a wake-up call about the fragility of even the biggest systems we rely on. And that’s when it hit me: this is what cloud architecture is really about. Lessons Reinforced From the chaos came clarity. Every principle I’d studied in my ALX Cloud Architect track suddenly had real weight: High Availability isn’t just a term — it’s your safety net. Multi-Region Design matters because failures do happen. Monitoring and Alerts aren’t optional — they’re your early warning system. Fault Tolerance isn’t about preventing crashes; it’s about recovering fast when they happen. It was one of those moments where the theory became alive. The Way Forward After the dust settled, I found myself more inspired than frustrated. If AWS — the gold standard of reliability — can stumble, it only proves that no system is perfect. As cloud professionals in training, our mission isn’t to eliminate outages. And maybe next time an outage strikes, we’ll be the ones explaining why it happened — and how to prevent it from taking everything down.  ( 7 min )

It's relatively simple these days to spin up an OpenTelemetry demo and / or auto-instrument services with OpenTelemetry. That's fine - when it works - but it's when something breaks that perhaps you realise you don't quite understand what's going on under the covers. I've lost count of the number of times customers have reported "broken traces" to me as they flow through an uninstrumented tier, a load balancer or a queue. In the following video I show precisely how distributed tracing using OpenTelemetry is able to do what it does (for HTTP) by spinning up two Python FastAPI applications, instrumenting them using OpenTelemetry and demonstrating that the traces are "broken" in Jaeger. Then I solve the issue (hint: it's all about propagation). The code for all of this can be found here: https://github.com/agardnerIT/python-fastapi-requests-traceparent  ( 6 min )

Every new capability means another bespoke, brittle integration. You’re not building a streamlined agent; you’re managing a chaotic switchboard of incompatible plugs and sockets. This fragmentation is the silent friction slowing down the development of genuinely powerful, multi-talented AI systems. What if there was a universal standard, a common language for LLMs to talk to tools, data, and services? Enter the Model Context Protocol (MCP). …  ( 12 min )

Memory leaks are a common issue in Node.js applications, especially when running inside containerized environments like Kubernetes. A memory leak occurs when an application keeps allocating memory without releasing it, leading to increased memory usage and eventually to container restarts or crashes. Here’s a typical graph of what a memory leak looks like: memory usage constantly increasing over time until the pod is restarted. Unclosed Redis or database connections Global variables accumulating data Event listeners that are never removed In short: memory leaks happen more often than you think, especially in complex services. And the tricky part? You won’t always see them in your local environment, since production traffic and timeouts behave differently. In our case, for example, the lea…  ( 8 min )

React Component GPT: We need a GPT that understands our React components, knows our CSS variables, and can spit out code that's ready to use. This isn't about general knowledge; it's about our knowledge. The standard GPT knowledge upload is fine for broad docs, but for precise component generation, we need control. That's where Actions come in. Our design system lives in zeroheight. Our CSS variables are in a .css file. Our React components are in .jsx files. These are all discrete sources of truth. A generic LLM has no idea how they connect. If someone asks for a "primary button," it might give generic HTML, not our Button component with --color-brand-primary. Unacceptable. We build an API. This API becomes our "knowledge retrieval service." The GPT uses Actions to call this API when it…  ( 7 min )

When I started building my own startup, I had one goal — to turn ideas into something real fast enough to test if people even cared. That’s the truth most founders learn the hard way: it’s not about building a perfect product, it’s about learning fast and adapting even faster. In 2025, speed is everything. The tools are smarter, AI is everywhere, and customers expect products to work right out of the gate. But despite all that, the fundamentals haven’t changed — execution, clarity, and discipline still win. Here’s what I’ve learned while building and launching MVPs (Minimum Viable Products) for startups and for my own company, EulerHive. Week 1: Define the Core Problem, Ruthlessly Most startup ideas fail not because they’re bad, but because they solve the wrong problem. When I began, I use…  ( 8 min )

How we evolved from Git chaos to a workflow that actually works for agency client projects "Which branch has the latest changes?" It was 4 PM on a Friday, and we had a client demo scheduled for Monday. Three developers had been working on different features, and nobody was quite sure which branch contained what. We had feature/new-dashboard, client-feedback-updates, johns-branch, fix-urgent-bug, and staging all containing different versions of the codebase. Merging everything took the entire weekend. The demo Monday morning included two features the client had specifically asked us not to include yet, was missing one they'd approved, and had a critical bug we thought we'd fixed in a different branch. That disaster forced us to acknowledge that our Git workflow, or lack thereof, was causin…  ( 14 min )

Yesterday, the internet had a bad day — and so did millions of users and businesses around the world. On October 20, 2025, Amazon Web Services (AWS) experienced a major outage that disrupted everything from streaming platforms and smart homes to enterprise apps and financial services. This wasn’t just another technical hiccup. It was a stark reminder of how fragile the modern internet can be when so much of it depends on a handful of companies. The issue began in the US-EAST-1 region — AWS’s most popular and densely used zone. According to Reuters, a problem with internal load balancing and DNS resolution cascaded through multiple AWS services. The result: apps and websites couldn’t connect to the servers they relied on. Among those affected were McDonald’s, Apple Music, Microsoft 365, Al…  ( 7 min )

I want to share with you a powerful AWS serverless pattern that uses two of my favourite AWS services: AppSync Events and EventBridge Pipes. Using these services we can combine the power of event-driven architecture with realtime user notifications. This article walks through how to build a demo application called Airspace Alerter, designed to showcase how these two services work together to deliver realtime user updates in a fully event-driven workflow. Airspace Alerter is a map based web application, but this isn't a blog about geospatial data handling (although I'm passionate about that topic too!). This blog focuses on event management.

Il giornalismo trattato come scienza comincia dalla definizione delle variabili: evento, contesto, attori, effetti. Senza un lessico condiviso, il racconto diventa aneddoto. Il taccuino è un laboratorio portatile: si formulano ipotesi, si cercano confutazioni, si annotano incertezze con la stessa dignità dei fatti accertati. Il campionamento delle fonti segue criteri espliciti: indipendenza, prossimità ai dati primari, competenza. Una testimonianza singola pesa come un indizio, non come una prova. La regola è triangolare: documento, voce diretta, osservazione sul campo. Quando due elementi concordano e uno diverge, si indaga il perché del disallineamento. La misurazione non è solo numeri. Anche le parole hanno metriche: frequenza, coerenza temporale, compatibilità causale. Le citazioni si trattano come segnali: si eliminano i “rumori” (opinioni non verificate, interessi nascosti), si puliscono i bias, si indicano i margini d’errore. Un buon pezzo espone non solo cosa si sa, ma quanto e con quale confidenza. L’etica è il protocollo di sicurezza. Proteggere le fonti equivale a proteggere l’apparato sperimentale: senza fiducia, i dati non arrivano. La proporzionalità guida ogni scelta: mostrare un nome, un volto, un dettaglio privato richiede di dimostrare l’utilità pubblica superiore al danno possibile. La trasparenza metodologica è parte del risultato. La pubblicazione chiude il ciclo e apre il successivo. Rendere disponibili i materiali, linkare gli archivi, spiegare passo per passo come si è arrivati alle conclusioni permette la replicazione da parte della comunità. Così il giornalismo non si limita a “informare”: costruisce una base cumulativa su cui altri possono testare, correggere e avanzare.  ( 6 min )

Introduction: The Hidden Cost of Poor Incident Follow-Up How did this happen again? Didn't we prepare for this? No engineering leader wants this message—especially after months of careful planning. Yet there we were: during our peak traffic spike, a critical customer-facing service slowed to a crawl, badly impacting customers exactly as we had seen before. Senior executives had to spend days personally reassuring frustrated customers, promising once again to finally address the underlying issues. The painful truth was that our infrastructure was outdated and architecture desperately needed refactoring. Instead, we’d spent months scaling hardware, applying patches, and tackling easy fixes—everything except solving the core problem. Our team knew what was needed, but the organization neve…  ( 12 min )

As a former teacher and curriculum developer, I've been curious about the potential of AI in scoring open-ended student responses. In this post, I'll walk you through my prototype design of an AI scoring agent, explain the code, and explore its initial outputs. In a follow-up post, I'll evaluate it's performance using multiple inputs, and reflect on what we can learn from how the agent approaches scoring tasks. All of the code and example outputs described in this article can be found in the GitHub repository. When I started designing my scoring agent, I wanted it to be able to do the following: Score student responses to questions based on a provided scoring guide Provide a score and an explanation describing why it assigned the score Be able to look up facts on the web (if needed) Have s…  ( 17 min )

What is everyone using!? The Diagram Tool Wars in the LLM Era Our Shared Frustration Greetings from Japan. Let's be honest. Every time I draw a diagram with Mermaid, I secretly pray to the coding gods, "Please, don't let the lines cross." It's no longer a technical challenge, but more like a game of chance. To put an end to this personal ordeal and find a better, data-driven solution, let's start a discussion. When documenting, what are people honestly using to draw diagrams!? Mermaid? PlantUML? Or are you still firing up draw.io in the end? Come on, tell me honestly! Tell me!! The common challenge developers face is always the trade-off between "ease of use" and "freedom of expression." Mermaid.js: Its ease of use is divine. It works on GitHub and Zenn. But doesn't it get fru…  ( 11 min )

Imagine this — you create a beautiful piece of software on your system. It runs perfectly, fast and smooth. But the moment someone else tries to run it on their machine, it breaks. One system says “library not found”, another says “version mismatch”. The software worked fine in your world, but not in theirs. This was the never-ending loop of frustration every developer once faced. In the early stages of software development, everything lived directly on the physical computer. Each machine had its own setup — operating system, installed software, dependency versions. That meant if you deployed the same code on ten different servers, it could behave ten different ways. To tackle this inconsistency, Virtual Machines (VMs) were introduced. A Virtual Machine acted like a computer inside another…  ( 8 min )

اینستاگرام: جایی برای دیدن، نه فروش اینستاگرام از اول برای فروش ساخته نشده بود ولی طی زمان با توجه به فعالیت کاربرانش شروع کرد به اضافه کردن قابلیت های فروشگاهی که متاسفانه با همه‌ی این حرف‌ها، اینستاگرام هنوز یکی از بهترین ابزارها برای «جلب توجه» و ساختن رابطه با مخاطبه. ۱. نیاز به ادمین دائمی در یک فروشگاه واقعی یا سایت فروش آنلاین، خیلی از فرایندها اتوماتیکن: ثبت سفارش، پرداخت، صدور فاکتور و... ۲. حسابداری و نظم مالی ۳. از دست رفتن اطلاعات مشتریان اعتماد کاربران جمع‌بندی: اینستاگرام بیلبورد تبلیغ تو اینستاگرام برای دیده شدن و شناخته شدن عالیه، اما نه برای مدیریت و رشد واقعی فروش. پس اگر الان فقط ازش برای فروش استفاده می‌کنی، وقتشه یه مرحله بالاتر بری: با ساختن سایت یا صفحه فروش اختصاصی، هم فرایندها رو اتوماتیک می‌کنی، هم اعتماد و دیتا به‌دست میاری. بذار اینستاگرام ویترین برندت باشه، نه تنها مغازه‌اش.  ( 7 min )

Every programmer has encountered it — that one phrase whispered with a mix of fear, awe, and exhaustion: “That part of the code is… legacy.” Legacy code — the mysterious beast that has survived through years of updates, countless developers, missing documentation, and still powers your company’s core systems. It’s both a curse and a miracle that it still runs. The “crap” part defines its internal quality (or lack thereof): Logic tangled like spaghetti: Hundreds or even thousands of lines in a single function, seven layers of if-else, and mysterious conditions that even the original author no longer understands. Random naming conventions: Variables like a1, temp2, dataList3, and functions called handle() or processData(). You read the name and still have no clue what it does. No comm…  ( 8 min )

Ever been worried about bots scraping your data, attackers brute-forcing logins, or your platform getting hit with a sudden spike in expensive operations? Without proper protection, a simple DDoS attack or bot script can cost you time, resources, and even thousands in third-party service fees (like SMS). Let me show you how to implement a thread-safe, high-performance rate limiter using Python, FastAPI, and Redis. Rate Limiting: Allow only X requests per Y seconds per user.

This can be done through a CDN link. Here's how we do it: import Pixalo from 'https://cdn.jsdelivr.net/gh/pixalo/pixalo@master/dist/pixalo.esm.js'; Next, we'll create a new instance of the Pixalo engine and set up our game canvas. We define the dimensions and background color, as well as the physics properties (in this case, gravity). const game = new Pixalo('#canvas', { width: window.innerWidth, height: window.innerHeight, background: '#031C1B', physics: { gravity: { y: 800 } } …  ( 9 min )

Why Cursor over Claude Code? Code-generation diffs are easier to review and roll back (the checkout system is great). You can test and use other models for different tasks (o3 for complex tasks, gemini-2.5-pro for creativity, grok-code-fast-1 for quick tasks, etc.).* Good IDE integration (e.g., accept/reject actions work great across the UI). *That said, I’m only using claude-4.5-sonnet since its launch. Use .cursorrules or similar to enforce behavior. For example: - Always use the project’s Tailwind colors. - Always use named exports with object parameters: `sum({ a, b })` instead of `sum(a, b)`. - Use "pnpm" instead of "npm" for all package-management commands. - Use the "use client" directive when using client-side state like useState, useEffect, etc. - Don’t modify package.json dep…  ( 7 min )

The cloud promised to simplify everything — agility, lower costs, and effortless global deployments in just minutes. But… what about security? Securing cloud environments has become far more complex than most expected, while opening a door for attackers is easier than ever. By its very nature, the cloud allows both employees and cybercriminals to access systems from anywhere in the world — as long as they have the right credentials and no additional controls are in place to stop them. This accessibility, one of the model’s greatest strengths, is also its Achilles’ heel. In this article, we’ll debunk some of the most dangerous myths about cloud security. The cloud isn’t exactly new — it’s been around for nearly 20 years (if we count from the launch of AWS). Yet, several myths continue to sh…  ( 7 min )

After a few comfortable years in the same flat, I found myself back in the nightmare that is the German housing market. Hundreds of applicants for one place, five-minute viewings, and forms that look like they were faxed straight from 1998. The worst part wasn’t even the competition - it was the Mieterselbstauskunft. It's a form that most landlords want. And you're gonna need it multiple times, thats just the housing market here. After hours of searching, it seems that there is just no real good way to fill it. To combat it, I built a small iOS app that lets you fill out and sign your rental self-disclosure digitally. Native form inputs, built-in signature with a handwriting-look, and a clean final PDF you can reuse in seconds. I know that developing it cost 20 times more time than I will save by using it. But if a handful of people start using it too, it will be a net positiv on the human-time bottom-line. If you’re curious, the app’s here: https://selbo-app.de/  ( 6 min )

🔍 Κατανόηση των Properties, Getters/Setters και Initialization στην C# Εισαγωγή Στη C#, τα properties είναι ο τρόπος με τον οποίο εκθέτουμε δεδομένα (fields) μιας κλάσης με ελεγχόμενο τρόπο. Αντί να κάνουμε απευθείας public τα πεδία, χρησιμοποιούμε properties με getters και setters, ώστε να μπορούμε να προσθέσουμε λογική ελέγχου, προστασία και συμβατότητα με serialization frameworks. 🧱 Τι είναι τα Properties Ένα property είναι ένας συνδυασμός: ενός getter, που διαβάζει την τιμή ενός πεδίου, και ενός setter, που τη γράφει. Παράδειγμα: public class User { public string Name { get; set; } } Αυτό είναι ένα auto-property, που σημαίνει πως η C# δημιουργεί εσωτερικά ένα private field για σένα. Μπορείς όμως να το γράψεις και πιο ρητά: private string _name; public string Name { get => _…  ( 8 min )

This is a submission for the Auth0 for AI Agents Challenge I built Snape, an AI agent that can manage your GitHub account — from listing repositories to performing actions like checking issues or commits — all through natural language prompts. Instead of typing out API calls or clicking through dashboards, users can simply say things like: “List my private repos from the Snape workspace” “Show me the open issues in my nextjs project” Snape will understand your intent, securely fetch the data using your GitHub access, and respond conversationally. The AI is workspace-aware — meaning different teams or users can manage their own connected GitHub accounts separately, with proper permission checks. Agent Snape Web application GitHub repositories Auth0 acts as the secure bridge between users, t…  ( 7 min )

Fine-Tuning LLMs: Avoiding Catastrophic Forgetting with a "Warm-Up" Approach When adapting pre-trained Large Language Models (LLMs) to specific tasks, a common challenge arises: catastrophic forgetting. This phenomenon occurs when the model's performance on the original task suffers significantly after fine-tuning on a new task. To mitigate this issue, we recommend using a "warm-up" approach with smaller learning rates. Why "Warm-Up"? The "warm-up" phase involves gradually increasing the learning rate from an initial small value to a larger one. This approach helps the model to: Stabilize the pre-trained weights: By starting with a small learning rate, you prevent the model from making drastic changes to its pre-trained weights, which are essential for its original performance. Adapt to the new task: As the learning rate increases, the model can learn to incorporate new knowledge without forgetting its original capabilities. Prevent overfitting: The ...

Steal Jeff Su’s CORE productivity hack—taught to over 6,600 Googlers—which boils down to four simple steps: Capture everything the moment it pops up, Organize with zero friction, Review in scheduled sessions, and Engage by time-blocking your to-dos. It works with any app or notebook you already love and becomes second nature in about two weeks, so you can finally stop relying on memory (or sheer willpower). In his video (with handy timestamps), Jeff breaks down exactly why CORE sticks, walks you through each phase in action, and hooks you up with his blog post, newsletter, favorite prompts/templates, a full Workspace Academy course, plus his own Notion command center and gear recommendations.
